I've been in contact with Stefan at Hongyuv about their ultrasonic anemometer that is plug and play for the Davis VP2.
http://www.hongyuv.com/en/product.php?id=63
The price was fair, but the specs were similar to the Davis anemometer and there was no heating option. I emailed him my concerns and he replied that they have a higher accuracy version and one with an automatic heater option (turns on at 0C) and the option to go cabled instead of solar powered.
Direct from the email (I hope he doesn't mind me sharing with the community)...
Yes, we also have another model that support heating function and higher accuracy..
Attached is introduction of HY-WDS2E ultrasonic anemometer for your info.
We can modify its output to be compatible with Davis Vantage Pro2 and without solar panel.
You can power it up with 5~30VDC, power consumption of it is 5mA@12VDC.
Power supply of heating is 12-24VDC: 120mA@12V (once power supply of heater is connected, heater will automatically turn on once the temperature outside is around 0℃)
Price of HY-WDS2E ultrasonic anemometer without solar panel is 430 USD/UNIT/FOB CHINA (heating function included.)
The solar panel will cost extra 50 USD.
Actually, we've tested WDC2E, which consume 18mA@12VDC through out winter in Chengdu,China.
It's cloudy here.
We think WDS2E will work for you, and you don't even need to turn on heating.
Do you know WindSonic from Gill?
Ours are similar to it, it don't have heating function, but still work under cold weather.
Our WDS2E won't fail unless accumulated snow/ice on platform is exceed 10 mm, which we never encounter yet.
Attached is user manual of HY-WDC2DVSE for your info.
The only different between it and HY-WDS2DVSE is ultrasonic anemometer(the one I recommend you with heater this time)
By the way, I forgot to tell you that power supply by cable is available.
We can remove solar panel and leave 4 cables for power input.
Two for anemometer, the other two for heater.
Attached are 2 PDFs he sent me. I'll be contacting him again today. If anyone has any specific questions I can add them to my email. So basically, he's quoting me $430 USD for a cabled, heated ultrasonic anemometer with +/- 2% accuracy that is plug and play with a Davis VP2.

Don't forget that the LCJ ones have a similar performance and are self-powered and VP2-plug-compatible, though not heated (but where does the power for this come from?) and not as cheap though still not bad for an ultrasonic - but they are made in France from a company with a long pedigree in this type of anemometer and not China. Details on our website if anyone is interested:
www.weatherstations.co.uk/lcj-ultrasonic-anemometer.htm (http://www.weatherstations.co.uk/lcj-ultrasonic-anemometer.htm)

We average 75"/190cm of snow each season so the non-heated options are a concern to me. I know Ryan at SI is going to be trying out one of these anemometers and if all goes well, he may be selling it on his site. Of course he's in FL so heating and solar is not an issue for him in the winter.
-
Thought I'd add this test report he sent me.
If you go the power cord and heater route, you could have both the anemometer and heater powered by the same cable. The RJ11 cord to the ISS/transmitter comes with 13m of cord. Standard power cable length is 4m, but he said they would do a custom length for extra cost. He said shipping to the US via UPS is $35.

I am VERY interested in a reasonably priced heated ultrasonic anemometer.
But it would have to be completely plug & play (compatible) with Davis. Other than the additional power requirements for the heater.
Even though I currently use Weather Display for it's website tags support,I don't want to be dependent on it. My primary data storage/archives are with WeatherLink and to a lesser degree MySQL via Davis WDTU.
The Hongyuv introduction documents lists the power requirements as DC 5-30V, 10ma@12V (without heater). I would like to know what they are WITH the heater.
Added: Note it would need to be compatible with the Davis 6332, VP2 Anemometer Transmitter Kit

It looks like I'm going to bite on this. I've had a good email correspondence with Stefan there and I know Ryan W will be trying one of their ultras and may add it to his inventory if all goes well. The WDS2E with heater, no solar panel, Davis compatibility, and 20m of power cord (2 wires for heater, 2 for power) will cost me $489. The heater automatically turns on at 0°C. I may install a switch near the plug that will allow me to manually turn off the heater. It really doesn't need to run 24/7 in the winter. I posted the heater power requirements in the first post.
And it should work no problem with the Davis 6332 (I use one too). You just need to set the wind cup size to "other" so that the VP2 doesn't make any adjustments to the raw data. We'll see how it goes...I'm tired of bearings going on my anemometers after a couple years.
The ABS plastic with this concerned me, but Stefan told me it's UV stabilized like the Davis rain cone. Still, I think I'll stick with the black option instead of the white (you have the choice of either).
The only bummer is you're stuck with the Davis resolution of 1mph.
-
Well, it's on its way. I'll give a review on it once it arrives. Stefan was great to deal with which eased my worries about ordering overseas. The WDS2E basically looks like a knock off of the Gill WindSonic.
-
Hongyuv has a number of great "looking" weather stations. If they had a US distributor they could take the market by storm. I always thought if you could get a Vaisala WXT 520 knock-off that is solar powered and with a price point around $599.00......
-

Let me know how the test goes. Looks interesting
-
I am also very interested and will be monitoring this project.
I think I should be able to afford the sensor in October. Hopefully some testing results will be known by then and that will give me time to receive it and install it before winter.
Dennis
-
I wonder if the Davis console/logger is unnecessary in all this? I mean, why not just use a Raspberry Pi to collect the data from these sensors?
-
To me the Davis compatibility is very important as I have Weatherlink data going back to 2003 that I want to append to.

I hear ya. I have WL data from this location going back to 2006 and back to 1996 at my previous location with my WMII. It's hard to let go. lol
I think I'm going to go the Meteobridge Pro/Nano route. I can keep WL datalogs for continuity, but widen my sensor and data options with the MB.

So convert your Davis WLK files to SQL DB and that is the end of it.

Here’s a pic from Stefan of my HY-WDS2E customized for the VP2. It was shipped a couple days ago and is scheduled to arrive Thursday. It’ll take a little time before I get it installed. I will probably put a switch on the power wire for the heater so that it doesn’t have to run in the winter on dry days.

I noticed that it tops out at 90mph (40 m/s). I know some will say that any equipment will be lucky to survive those winds and, yet, we've heard reports from forum members about Davis anemometers recording such events. Just putting it out there.
Also what diameter pole will this fit on?

My version is 0-60m/s (134mph). I posted the PDF with the specs in my first post.
Pole diameter is 50mm so basically 2".

OK, thanks. Does anyone know offhand if a 2" u-bolt will fit through the mounting holes in a Davis anemometer transmitter?
My version is 0-60m/s (134mph). I posted the PDF with the specs in my first post.
The web page you linked to claims the max is 40 m/s. Didn't bother with the PDF because I figured the specs must be the same. I wonder which one is accurate?
-

It looks like it should. The inside dimension of the spacing between the u-bolt mounting holes is 1.6", outside: 3.2". So a 2.5" u-bolt looks like it would fit fine.
Note: this is measuring an older VP1 enclosure but I beleave they are the same as the VP2 enclosures.
Also, openvista, I'm intrigued by your anemometer pole. Can you please tell me a little about it? How tall is it? Is it standalone (I don't see any guy wires)? Where did you get it?
I am really getting to old and tired of climbing up onto my second story garage roof to perform maintenance on my anemometer. I would really like to switch to something ground base, but need 30-40 above the ground.

We have many >100mph without any damages in Davis vanes.

OK, good to know. Next time I take down the anny, I will run a tape measure across the transmitter to verify.
I use a 30ft Superior 3 telescopic flagpole (http://store.tele-pole.com/telescoping-flagpoles/30-ft-superior-three-telescoping-flagpole-reg-779-sale-579/ (http://store.tele-pole.com/telescoping-flagpoles/30-ft-superior-three-telescoping-flagpole-reg-779-sale-579/)). ValentineWeather also uses the same pole as do some other members (whose screen names escape me). I've recorded 50mph winds on it no problem. It's made out of 10 gauge aluminum and the manufacturer warranties it for ANY wind speed. It's pretty heavy when raising it up, but I'd say an average man in good health should be able to do so.
No, I don't use guy wires because there's no place for me to secure them properly as there are nearby obstructions. The top will move very noticeably in high winds, but I've never found it to be a huge problem, counter-intuitively. Compared to other stations (the nearby Coast Guard in particular), it seems accurate in both speed and direction, especially when averaged over 10 mins. The most important thing is that the base is perfectly true and level. That way, when it's at rest, it can easily pick up a 1mph wind and the directional vane requires minimal inertia to turn.

Stefan had mine customized. I posted 2 different PDFs of 2 different products in that original post. The HY-WDC2DVSE is the one they advertise as being compatible with the VP2. That has the same specs as the Davis anemometer and it isn't heated. I inquired Hongyuv about it and Stefan said they can make the better spec'd one (the WDS2E) compatible for the VP2 as well. I was able to choose the heater option, color (black or white), the Davis RJ11 compatibility, whether I wanted solar power or not, and the length of cord.

openvista,
Thanks for the information about the Superior 3 pole.

I have been anxiously waiting to hear how this sensor has been performing.
Any news?

Sorry guys. I'm going to need another few weeks before I get everything up and running. The Mrs. had some tragedy in her family and we were out of state for awhile. I'm waiting on a new 40ft telescopic mast too. Guy wiring that to my garage roof will be fun too. Hopefully the 40ft isn't too high.
-
Thanks dendrite.
Also, where are you planning on getting your 40 ft mast? That's what I need, the 30 ft previously mentioned is not high enough for me.
Dennis
-

I'm going to try one of those Channel Master 40ft telescoping ones that require guying. I have a 20 footer guyed to my garage roof now. People around me think I'm crazy, but if we can go higher then we go higher...because that's what we do. ;)

Thanks again dendrite.

Just saw this thread,
is there a full spec sheet of the heated ultrasonic anemometer? I see there's a tech "sheet" on the link given, but nothing much more than that. derrrr.... Just saw the two attached files on the first post!
Does the Davis ISS and Console capture and report in decimal-place speeds? As this unit reports 0.1m/s which is on the bounds of 0.22mph. The anemometer that comes with the David Pro2+ seems to only report in full mph values, nothing in decimal places.

Give me some time to test it out for confirmation (AC-DC adapter comes in on Sunday), but I believe you're limited to 1mph resolution using any anemometer on the Davis. I'm not sure if you could get more resolution using a Meteohub since it contacts directly with the ISS, but my hunch is it won't work. This is made to match the pulse output of the Davis cup anemometer

Not a problem, i anxiously await your findings. :)

Pretty sure that you're limited to integer mph values. Someone who knows the format of the ISS data better than me would be able to confirm but AFAIK wind speed data is transmitted from the ISS (or eg 6332) as a single byte and therefore there's an overriding limitation of integer speed values, ie 0-255mph!

You are correct...

So with that said, even with the higher resolution value of the anemometer wind speed/direction, the ISS to console is the limiting factor in this? I assume that no matter what I do, the decimal stops at the ISS? If so, that's quite the bummer!
-
Hey everyone. Sorry it has taken so long for me to test this out. We have some progress though...
Today I took down the telescopic mast and Davis anemometer. I've decided to forego the 40ft mast for now as the new/additional guy wires and roof mounts will be time consuming. I'm going to use the same 20ft telescopic mast I have now and use a mast to mast mounting kit to attach the two together.
https://www.amazon.com/gp/product/B003EAY89M
I'll mount the ultrasonic onto another small mast to get an additional 2-4ft of height. In the meantime I've mounted the anemometer onto a 4ft U-post, powered it up, and hooked it up to the Davis to see what I'd get.
Initially everything was great. I had a couple of hours of data with very good response. Since there's no moving parts there's no starting threshold so it was rare to see the console show 0mph. The 1-min sustained speeds are running about 50% of the 1-min gusts which is impressive considering it's only 4ft off the ground with trees and buildings in the vicinity.
My only problem is that I had 2 periods during the afternoon where I was recording winds of 50-100+ mph. There was a poor connection along the data line somewhere. After the first time, I unhooked everything (data and power connections) and then reconnected everything and the data came back fine. I left it alone the rest of the evening to burn wood in the fire pit and noticed a bit ago that more faulty high wind speed readings occurred for about 15-20mins. This time they came and went on their own. I opened up the anemometer transmitter and the plug was still firmly connected into the wind socket. When connected, there is still some wiggle room in there for the plug to slightly pull in and out. It's been reading well for a little over an hour now. So I'll keep my eye on it. I'll probably get it installed this weekend when I have a little extra help over here for lifting the mast back into the tripod on the roof.
Here's the link to my readings on MW...

Just noticed I'm getting bad readings again with spikes in the 20-30mph range. Then it goes back to the correct 0-3mph.

It seems to be aligning with some missed packets from the ISS. I have no idea what could be causing the interference.

I powered it up again this morning after giving it a good 6 hours of rest and it looked like the eyewall of Hurricane Michael the entire 20 minutes it ran. I shut it down again and will play with it more this afternoon after work.

Had the Mrs. plug it in to try it during the day and had the same result. My packet reception from the anemometer transmitter dropped from a steady 100% to 80-90% once it was powered up. So there definitely seems to be some sort of interference between the transmitter and anemometer. The overseas Davis stations use a different frequency, correct? Maybe Hongyuv didn't account for the frequency used on the US versions? I dunno...just brainstorming here. You can see the obs with wind data here and the ISS reception percentage is the 2nd to the last value if you scroll all the way to the right.

Do you know what the ultrasonic uses Stefan?

I thought that the ultrasonic was wired to the ISS?
Is it being powered by the ISS, or an external power supply? Could this be an under-voltage from the ultrasonic drawing too much power from the ISS? Ground loop if one or more AC transformers are in use?????

It's supposed to be powered externally. I'm using 12VDC. I forgot my meter at work, but the power supply I bought came as a 2 pack and I've had similar results with each. The cord to the ISS has the typical 4 wires connected into the RJ11 connector. I'm not sure what that power wire leads to on the anemometer side though.
-
Okay...maybe someone with more electrical and ISS knowledge can help me out here. ;)
First of all, I've been in frequent correspondence with Stefan on this issue and he has been providing terrific customer service. They're willing to ship me another ultrasonic sensor free of charge if mine is faulty. So I have 100% trust with him right now despite the problems.
Now, I'm noticing that I'm getting good data during the day when the sun is shining on the transmitter solar panel. When the shade sets in the data starts to go awry. I get a minute or two of bad data every 10 or so minutes and it picks up in duration throughout the evening until all of the readings are faulty. On Monday we had fog, mist, and drizzle the entire days with low solar radiation and the bad readings happened all day. Today the data was fine all afternoon until the shadows set in.
Again, this sensor runs on external 12VDC power and performs fine with solar radiation hitting the transmitter panel. What could be happening after the solar is lost? I should add that this is happening on two different transmitters too.
I'm assuming something is happening when the power source for the ISS shifts from the solar panel to the supercap. I considered snipping off the supercap from my older transmitter just for kicks and let it run off the solar and battery only, but I'm not sure if it would work with just the battery either. I want a long term solution too that won't cause me to drain through batteries.
Anyone have any ideas?

Power the ISS from wall power?????

Power the ISS from wall power?????
Good thinking. Looks like it uses 5V. Will I fry it with a 12VDC adapter?
-
I found a 2.4VDC adapter lying around that fit into the ISS connector and no luck. Still bad data.
-

Needs 5 volts.
-
Just remembered I have the adapter from the console. I plugged it into the transmitter and I’m still getting bad data with the 5VDC.
-
Let me get this straight. The order of power for the ISS...
1. solar panel...excess goes toward the supercap
2. supercap
3. 3V CR123 battery
Now if I use the 5VDC adapter will the ISS try running off of the solar and drain the supercap first? Is the supercap even being used once the external 5V is plugged in? Can the supercap be causing some kind of electrical interference? Maybe the supercap is simply just bad? I'm contemplating snipping the supercap right off and to force the ISS to only run on the external power and battery backup.

Answering your questions in order:
Yes, that's an approximately correct and approximately complete description of "order of power".
No.
Not if all the circuitry is working correctly.
No.
Perhaps.
That would be the next diagnostic thing to try.
However, given what you have done already, I suspect that the power circuitry (diodes) on the ISS board is not working correctly. Or.....
I can't tell from this discussion exactly how the 12v anemometer power relates to the ISS power circuitry. But I speculate that there's some cross-relationship. It's even possible that connecting the new anemometer has "blown" something (perhaps a diode or perhaps the supercap) on the ISS board.
One way to test would be to disconnect the new anemometer and connect the Davis anemometer and see what happens (day, night, with 5v power, etc.).

Thaughts/Questions
Is this the first one of these (heated, 12V power, non-solar) anemometers that has been produced?
I wonder, on the solar-powered ultrasonic anemometer, what voltage that solar panel is producing? If it's low (same as the Davis solar panel), there wouldn't be as much chance of a problem than if it's high.
The Davis anemometer is essentially a "passive" device. It has no voltage source of its own, and is just an on-off switch and a variable resistance. Correctly simulating that with an "active" device (a powered ultrasonic anemometer) is not exactly simple.

I believe this is the first one produced for the Davis. Hong Yuv originally tested this on a cabled VP2 and had no issues. Stefan has told me they are expecting a wireless VP2 to arrive in 5 days to test it on that.
It's running flawlessly again today with full solar power. I'll probably remove the supercap from my old transmitter and plug the sonic into that once the bad readings appear.
What's the output voltage spec of a Davis ISS solar panel? If my 5VDC adapter jack isn't working maybe I can snip off the solar panel and splice a (I assume) 3VDC power source to the solar panel wires?

Your Davis solar panel is OBVIOUSLY fine.
I believe this is the first one produced for the Davis. Hong Yuv originally tested this on a cabled VP2 and had no issues.
The power arrangement on a cabled VP2 is ** A LOT ** different. [In addition to no solar panel, and no supercap and no battery...]
What's wrong with the idea of going back to the Davis anemometer for 24 hours? That should clearly show where the problem is, without cutting the supercap or anything else.
-
I know the solar panel is fine, but it doesn’t do me a lot of good at night. I’m just looking for a power entry point that actually works. I’m not great at these electronics like some of you guys either so I’m limited onmy abilities. ;)
I’ll plug the Davis in if the sonic starts failing. The shadows are beginning to hit the solar panel now. I guess we’ll see if the sonic is frying something in these transmitters or if there’s another issue.
Thanks for the help.
-
The sonic started its 10 minute frequency of bad readings after solar got low so I plugged the Davis anemometer in. It's been working fine for over 20 minutes.
I'll probably have to wait for HongYuv to receive their wireless VP2 and perform their own tests. They've been very helpful and eager to work out these kinks.
-
The sonic started its 10 minute frequency of bad readings after solar got low so I plugged the Davis anemometer in. It's been working fine for over 20 minutes.
The questions will be:
1. Does the Davis anemometer continue to report correctly for a complete cycle through the night?; and then
2. Does the Davis anemometer continue to report correctly with the 5V adapter plugged in, and the battery removed? (for a complete test, also cover up the solar panel and wait 12 hours to be sure the supercap is not involved).
I'd appreciate a report here. If the above test(s) fail, it's possible that the ultrasonic anemometer damaged your ISS. If the tests pass, then we could conclude that the ultrasonic anemometer is messing up the ISS, but not damaging it (yet).

Well I temporarily mounted the sonic up on my roof tripod (no 25ft mast yet) and it is almost 7PM EDT and it is functioning properly. I'm starting to think there was some sort of earth/ground loop issue while I had it mounted down on the ground at 5ft. I don't know enough about how these occur so maybe someone can explain to me what could have been causing it and why it's working now. All of the connections are the same as they had been before. I'll do some research myself too, but it's nice to at least see it running. Maybe moving the anemometer improved the earthing?
Also, does anyone know why the problem would go away during the day with the solar power kicking in?

You have not supplied enough information for anybody to reasonably speculate on any of those questions.
And, of course, the manufacturer hasn't supplied that sort of information, either.
However - if it's POSSIBLE for earthing/grounding to cause this set of symptoms, then there is some DESIGN DEFECT in the anemometer. It might be a very small design defect - but it would be important.
You can ask your manufacturer contact the same questions, of course.

Dear All,
This is Stefan from HONGYUV, I upload principle of Davis anemometer and wind vane for your info.
Anemometer: a passive switch signal source powered by ISS(3V)
Wind vane: a digital potentiometer source output 0-3VDC correspond to 0-359°
There is no way that our ultrasonic anemometer will damage ISS.
We've got our wireless VP2 and we are now trying to recur same malfunction, but temporarily without any result yet.
Theorectically speaking, considering Davis anemometer and wind vane is commonly used, there should be no difference between cabled and wireless VP2 concerning data collection on them.
I also uploaded a spray testing video on our WDS series products, from which we can eliminate potential suspect on its water-proof performance.
In this testing, no malfunction was found.
I didn't check this forum out frequently but I surely will post new test result here later.

Perhaps a language problem - that's not exactly a correct description. But OK.
There is no way that our ultrasonic anemometer will damage ISS.
Easy to say. Perhaps correct. Note that the anemometer has a separate power supply of 12 volts, with separate grounding, etc., and needs to supply a PASSIVE switch signal source (passively referenced to the ISS power), and "a digital potentiometer source output 0-3VDC" actively referenced to the ISS power and ground. That's not simple.

Theorectically speaking, considering Davis anemometer and wind vane is commonly used, there should be no difference between cabled and wireless VP2 concerning data collection on them.
...other than the fact that, in the cabled system, power is supplied to the ISS from the console power (via 2 wires in the cable, the other 2 being the RS-422 differential signaling from the ISS to the console) - while in the wireless system, the power is supplied by the ISS itself, and there's no cable down to the console. But in this case, a cable to the ultrasonic anemometer which has it's own separate power source and ground, with its own cable.
I'm not saying there's a design problem - just that it's easy to claim there is not. [But dendrite did have a problem, with one of the mounting configurations]
There are lots of variables here. Separate-or-connected grounding would be one of them.

The different ways of power supplying for cabled/wireless ISS doesn't affect its data collection on wind data.
It's internal circuit board designment only decides when/where should it get power from.
To the best of my knowledge, the priority of power supplied in orders:
1.solar power
2.supercap
3.3V battery
We've got a brand new wireless VP2 on running to find out the reason.
If no faulty were found, we will send dendrite a new ultrasonic anemometer for replacement and then have recalled one tested again on our wireless VP2.
-
The different ways of power supplying for cabled/wireless ISS doesn't affect its data collection on wind data.
True, provided that the wind data consists of:
Dry (passive) contact closure for wind velocity; and
Dry (passive) simulation of a variable resistance for wind direction.
The original description of wind speed was "a passive switch signal source" - but the word "source" is confusing.
I note that the description of the wind direction was "source output 0-3VDC" - which is not the same as a variable resistance. Of course, perhaps there is a language translation difficulty.
Again, I'm not saying there's a problem. And I don't know what circuitry is in the ultrasonic anemometer to provide a contact closure and a variable resistance. I just understand that it's not exactly easy to do that in an actively-powered instrument, under all conditions of grounding and power supply sources.

You're right Dalecoy.
Sorry for my improper expression.
Let me say it in another word.
Wind speed output in a way of passive(dry) swtich signal (power supplied by ISS)
Wind direction output in a way of 0~3VDC voltage signal(you can also call it variable resistance.)
If you have meter to measure wire of wind direction output, you can easily prove that I am telling you truth.
I am, not a hardware engineer, trying to explain you those to explain why our anemometer won't be harmful to ISS.
-
Attached is the wireless VP2 we are testing now.
The WDS2DVSE is powered by our solar panel.
We definitely will fix dendrite's problem ASAP.
-
If you really want to simulate my setup shouldn’t you be testing it with a 12V AC adapter? How much voltage does the solar panel provide again?
-

Yes, they should be testing with the 12V AC adapter.
"Wind direction output in a way of 0~3VDC voltage signal(you can also call it variable resistance.)"
No, I can't call a 0~3VDC voltage (which implies a neutral/ground reference), a variable resistance (which has no neutral/ground reference until connected).
If you have meter to measure wire of wind direction output, you can easily prove that I am telling you truth.
I would use an ohmmeter to measure resistance. Is that correct?
-
Of course, yesterday we were testing solar powered version, they are waiting to be shipped out.
We test 12VDC powered WDS2DVSE from today.

O-3V realtive to what? I'm no electronics expert, but shouldn't it be using some sort of common rail so that the output voltage is some fraction of the input reference voltage relative to the input ground?

IIRC the red wire in the 4-conductor anemometer cable is effectively the ground/earth/common connection, so the direction indication should be +(0-3)V relative to that.
The LCJ DZP solar-powered ultrasonic anemometer (for further info see our main website at https://www.weatherstations.co.uk/lcj-ultrasonic-anemometer.htm (https://www.weatherstations.co.uk/lcj-ultrasonic-anemometer.htm)) is a drop-in replacement for the standard 6410 anemometer and uses the standard 'RJ11' connector. So assuming this alternative ultrasonic unit works in a similar way to the LCJ, there's no reason in principle why the interface as described shouldn't work OK.
NB I wasn't there myself, but I'm told that there were quite a number of newly introduced ultrasonic anemometers on show at the Amsterdam weather station trade show a couple of weeks back. These were mostly from Chinese manufacturers and typically somewhat higher-priced units (though not high-end). These were part of general weather stations (ie rather than 6410 replacements) and many apparently were using (copying?) the Gill MaxiMet type of design. But it is an indication that ultrasonic anemometers do seem to be moving more into the mainstream, albeit still significantly higher-priced than eg 6410.

Not exactly, johnd
The direction indication (if it's a voltage) should be some percentage of the voltage difference between the red wire and the yellow wire.
Now, what's the voltage on the yellow wire? That's whatever is supplied by the SIM (at least with the standard Davis anemometer). So, it would almost certainly be something other than 3.0 V. I don't know the internals of the SIM, but the voltage is (normally) supplied by the solar/supercap/battery/external supply.
Oh - but maybe the ultrasonic anemometer is putting 3.0 Volts on the yellow wire? Hmmmmmm. Referenced to what "ground/earth/common"? Oh - maybe the ultrasonic anemometer is connecting the ground/earth/common of it's external 12V supply to the ground/earth/common of the SIM? Or.........?????
The correct simulation would be a variable resistance (potentiometer) simulation, not a voltage. That has no "common" reference. That's why I've been asking about measuring it with an ohmmeter.
-
That is what I was trying to get at, it shouldn't be just outputting a voltage (without referencing to what), it should be outputting a fraction of the reference voltage supplied by the ISS referenced to the ISS common line (as the solar and UV sensors work). I suspect the ISS just measures the returned voltage rather than measuring the resistance via a voltage and current calculation.
-
Aren't we just debating semantics or terminology, at least to a large extent though?
My picture (which CBW of course) is that when the current direction is read the voltage at the wiper relative to common is 'measured' (which should be equivalent to measuring the resistance) and eg applied to an A/D converter. Why does it matter whether that voltage is derived from the ISS supply voltage or effectively emulated by a different type of anemometer as long as both are referenced to the same ground? Of course the reference/supply voltage might not be exactly 3.00V for both voltage sources and so is a potential source of error, but at a guess both will be 3.0±0.1V or better and so won't be a major source of error in the context of direction. And maybe the circuitry of a well-designed alternative anemometer could provide a correction even for that discrepancy.

It's not "the voltage at the wiper relative to common is 'measured' (which should be equivalent to measuring the resistance)".
It's the voltage at the wiper as a percentage of the total voltage across the potentiometer.
Assume, for instance, that the Davis solar panel is powering the SIM and the solar panel voltage is 2.8 volts - and the anemometer direction signal is supplying 2.95 volts. What's the direction of the wind? [NOTE: This is just an example - I have been asking for more information, as you know]
But it's not just semantics or terminology - especially in the case where the anemometer is being powered by an external 12V supply. The anemometer will have internal circuitry with voltages referenced to the anemometer common. The SIM will have internal circuitry with voltages referenced to the ISS common. You said: "as long as both are referenced to the same ground", and that may be a very important point - if the anemometer is supplying a voltage, rather than a resistance (potentiometer) that does not have a common/ground reference (like the Davis anemometer).
Also, do the anemometer and the ISS have a "frame ground" in any situation? Like an external power supply for the ISS? What if those "frame grounds" are actually connected together, by mounting them on the same tower, or .......
And finally, the above discussion is where the cabled VP2 differs significantly from the wireless model. The cabled VP2 clearly has a "common reference" (one of the wires from the console to the ISS).
There are a lot of variables here - I'm not saying there's anything amiss. But the "wireless VP2" and "anemometer supplied by an external 12V source" has been reported here as having problems. That would be understandable if (for instance) that anemometer is truly supplying a 0-3V directional signal, (with perhaps a common reference different from the SIM).
One key question (in my opinion) would be whether the anemometer direction can be measured with an ohmmeter.
-
Footnote: It's also possible that the ultrasonic anemometer is supplying a "reference voltage" (perhaps 3.0 volts) on the yellow wire (the wire that goes to the other end of potentiometer of a Davis anemometer).
I have no idea what that would do, given that the "reference voltage" normally comes from the SIM. And is "normally" less than 3.0 volts, at least during part of the day, with a solar-powered ISS.
-
OK, let's make some assumptions:
1: Dalecoy is correct that the voltage supplied by the ISS to the anemometer pot varies with battery/supercap state.
2: The processing inside the ultrasonic anemometer is digital not analog.
3: Follows from 2, that there is a digital to analog conversion taking place to generate a voltage output for direction.
The logical way to make this direction voltage output ratiometric would be to use the ISS pot voltage as the reference voltage for the D/A conversion. That's how I would build it anyway.

Yes, that would make sense. Of course, "ISS pot voltage as the reference voltage" means using the voltage between the ISS red (- / common) and yellow (+) wires. Then proportionately supplied to the green (direction input) wire.
Note that there are 4 wires involved - the black wire handles the wind speed pulses (pulsing to the red wire).
Now, handle all of that with two separate power sources (one roughly 3 volts and the other roughly 12 volts). And remember that the "commons" of those two power sources might be connected in some installations, and might be UNconnected in other installations.
Again, I'm not saying that there's any design problem (although we haven't heard from Stefan from HONGYUV in 4 days or so). Just saying that this "active interface" isn't exactly as simple as the "passive interface" of the Davis anemometer.
-
The anemometer works fine with the ISS running on solar? Craps out after dark? Sounds like a bad filter cap (leaky) somewhere in the 12 volt portion.....

I was wondering if the wind direction could be implemented with a digital potentiometer. It is a "pot on a chip" and behaves just like a mechanical potentiometer.
Here is an Analog Devices app note: https://www.analog.com/media/en/technical-documentation/application-notes/AN-1121.pdf (https://www.analog.com/media/en/technical-documentation/application-notes/AN-1121.pdf)
Indeed, Stefan's diagram here shows a digital potentiometer for the vane.
(it's under the "generalities" and in the diagram)
https://www.wxforum.net/index.php?topic=34832.msg361908#msg361908 (https://www.wxforum.net/index.php?topic=34832.msg361908#msg361908)
(https://www.wxforum.net/index.php?action=dlattach;topic=34832.0;attach=33481;image)
Also, if you look at WxTech's excellent resource page (http://www.wxforum.net/wxtech/Anemometer-Vane.htm) on the Davis wind set, the "excitation voltage" for the direction pot is pulsed out of the SIM. Hence, the digi pot makes more sense than a DAC output scheme.

Good point, I had forgotten that it would likely be pulsed like the other ISS sensors. Since the voltage pulse and the reading are synchronized the D/A reference concept would still work.
-
And remember that the "commons" of those two power sources might be connected in some installations, and might be UNconnected in other installations.
Are you suggesting that the anemometer PSU and the Davis PSU would both have one side of the DC output grounded? Otherwise the only common link would be when the anemometer is connected to the ISS.

I am suggesting that, under some circumstances, and depending on the design/construction of the anemometer, they both could have one side of the DC output grounded.
In the case of the Davis unit, an external 5V supply could have its "common" grounded, either on purpose or by accident.
Remember, also, that "common" is not necessarily "ground". For instance, if the devices were mounted on the same metal pole that was insulated from the ground - but both devices had their "power supply negative" connected to the metal pole, that could be a problem - depending on design.
The point is - the manufacturers don't have any control over how devices are physically mounted or connected. Anything that might have it's "power supply common" exposed, must be carefully considered. And "power supply common exposed" is a possible characteristic of anything that has an external power supply.
Of course, the internals of many devices like these are proprietary - so we can only judge by experience.

That might work. I don't have any experience with that device, and I read the application note (twice). The examples in the application note show it performing like a potentiometer, with either pushbuttons (up and down) or an "incremental digital encoder" (e.g., a counter) stepping up and down.
I could not tell from the application note what happens at the end-points. The mechanical potentiometer in the Davis anemometer obviously goes around completely (transitions from maximum resistance to zero resistance as it passes through "north").
What happens with the digital potentiometer when the "count" is at maximum, and then is told to go "up"????
-

It depends on which part you select. The application note doesn't really explain the operation that well. However from a typical spec sheet:
"Additional clock pulses on the CLK pin are ignored when the wiper is at either the 00H position or the 7FH position." This simulates the mechanical stops in a regular pot.
I have used digital pots in many designs. Most of mine have been processor controlled using either I2C or SPI interface. Either of these methods would overcome the "stops" because you can constantly write a completely new value.
-
Here is ADI's selection table for 20K digi pots:

This isn't necessarily what this ultrasonic anemometer is using, but it might give further insight.
Note the various interfaces available, as rdsman has noted.

Hi everyone.
After my discussion with our engineer.
It's not just a simply voltage output.
ISS will supply a 3V pulse to PIN:OE, then anemometer feedback a voltage from 0-3VDC corresponding to 3~359°.
Attached is photo I measure.
Let me explain you how I can keep measure this voltage:
I wired OE terminal to an internal power supply on our circuit board where a 3.3VDC voltage is supplied.
The wind direction is round 180°,I measure voltage 1.536V.
By the way, we didn't recur malfunction dendrite mentioned, so we decided to send him another set which can be powered by our solar panel or 5VDC.
We will recall his WDS2DVSE and test it on our wireless VP2.
-
ISS send this 3V voltage pluse every three second.
That means ISS sample every 3 s, it's written in VP2 user manual.

Looks like Ryan has the HongYuv HY-WDC2DVSE ultrasonic anemometer for sale on his site now.
https://www.scaledinstruments.com/shop/davis-instruments/hongyuv-hy-wdc2dvse-ultrasonic-anemometer-for-vantage-pro2/
That's the solar powered one with similar specs to the Davis anemometer and no heater option. It looks like it comes with all of the hardware minus the batteries though.

I have five units with heater, but I have not had time to post them yet. Overall selling price is higher than I anticipated, I got whacked by a 25% import tariff which has been imposed on certain imported Chinese goods (ouch).

dendrite,
Whats the status of your testing? Should I infer from the lack of updates it's not going well?
I would like to get one of these units, with heater, if they work out as a direct replacement for the Davis anemometer in a VP2.
Had my anemometer freeze up from frozen rain again last night, it did thaw out this morning though.

Hi Dennis,
Since my last email with Dentrite on 10th,Jan,2019. I tried to contact him serveral times by email without success.
It's plug and play with heating function make it free from stopping working under snowy days.(you have to supply extra 12-24VDC for heating).
We guarantee you 100% refund if it don't work for you.
You can make further contact to us at stefan@hongyuv.com.
-
Did you get this working and how is is running?
-
Anybody have any updates here? I really like the idea of the HY-WDS2DVSE but I would also like to be able to collect the detailed data. Emailed to see if I can get both outputs (I know, greedy). Anyone else try one out?
-

Quite pricey though....

Its pricey, but IMO reasonable when you look at the others.. I gather it is simply an LCJ rebranded which is a pretty good price break if true.
-

Yes, that's essentially correct, as per previous discussions here. The Davis version is not yet available though, but the original LCJ version has been on the market for a few years now.

I suspect 'other' would be the best option since I'm guessing this doesn't apply any secondary correction to the raw speed values for either speed or direction and there's probably no good data on what the LCJ unit needs (if indeed the idea of secondary correction is relevant at all).
-
Per the docs, you use 'other' as the cup size.
4.Configuration of the DAVIS VP2
The anemometer cups must be set to "OTHER" in the Setup Menu.
I was interested in it, but the $400+ price is a major disincentive. For me, the operating range of 5F-131F wouldn't be an issue, but for colder climates, it could pose a problem. I suppose anything with precip and <32F could pose a problem with the current mechanical anemometer/wind vane just as well.

No, it wasn't that you missed it. It is that the version of the manual that was linked in prior message was from Scaled Instruments is different and has that information missing. The Davis manual that I linked is a different version of the manual.

I ordered one as well.
I hope it can handle Michigan weather. I was worried about snow covering the solar panel, but the LCJ manual claims; The battery supplies sufficient voltage for 23 days without sun.

You did see up top where it's only rated down to 5F, right?
-
Mine is a secondary wind set. It will be mounted on my ISS tripod. I did order the mast kit to extend it a bit above the rain gauge.
I primarily use this for lower wind data to see what affect the wind has on the rain collector.
This is more of an experiment toy than anything else.

I tried the hy-wds2dvse out and ended up sending it back. I had the heated version and it worked great in snow, cold, and strong winds. The wind speed and direction were accurate. However, whenever it rained and the sensor got wet, it failed and would report 0 wind speed for 1 to 3 hours until the sensors dried off. This is a known drawback of this anemometer. I suppose if that is not a concern to you, then I would recommend this anemometer. However, I need wind data when it rains and don't want to wait a long period of time after it rains for the data to come back.
-
Nothing like a PWS component that fails because of...wait for it...rain.
-
i'm currently develop a new one with metal construction and 200+ kmh of max wind speed. I hope it's ready in next months. [tup]
-
How is the anemometer performing?
I'd Like to hear about the reliability and performance and accuracy.
My anemometer is showing signs of failure.
So I might be interested in purchasing the 6415 also.
Instead of buying a 185€ 6410.
The 6415 is priced at 539€ here.... 😕

I've been in contact with Stefan at Hongyuv about their ultrasonic anemometer that is plug and play for the Davis VP2.
http://www.hongyuv.com/en/product.php?id=63
The price was fair, but the specs were similar to the Davis anemometer and there was no heating option. I emailed him my concerns and he replied that they have a higher accuracy version and one with an automatic heater option (turns on at 0C) and the option to go cabled instead of solar powered.
Direct from the email (I hope he doesn't mind me sharing with the community)...
Yes, we also have another model that support heating function and higher accuracy..
Attached is introduction of HY-WDS2E ultrasonic anemometer for your info.
We can modify its output to be compatible with Davis Vantage Pro2 and without solar panel.
You can power it up with 5~30VDC, power consumption of it is 5mA@12VDC.
Power supply of heating is 12-24VDC: 120mA@12V (once power supply of heater is connected, heater will automatically turn on once the temperature outside is around 0℃)
Price of HY-WDS2E ultrasonic anemometer without solar panel is 430 USD/UNIT/FOB CHINA (heating function included.)
The solar panel will cost extra 50 USD.
Actually, we've tested WDC2E, which consume 18mA@12VDC through out winter in Chengdu,China.
It's cloudy here.
We think WDS2E will work for you, and you don't even need to turn on heating.
Do you know WindSonic from Gill?
Ours are similar to it, it don't have heating function, but still work under cold weather.
Our WDS2E won't fail unless accumulated snow/ice on platform is exceed 10 mm, which we never encounter yet.
Attached is user manual of HY-WDC2DVSE for your info.
The only different between it and HY-WDS2DVSE is ultrasonic anemometer(the one I recommend you with heater this time)
By the way, I forgot to tell you that power supply by cable is available.
We can remove solar panel and leave 4 cables for power input.
Two for anemometer, the other two for heater.
Attached are 2 PDFs he sent me. I'll be contacting him again today. If anyone has any specific questions I can add them to my email. So basically, he's quoting me $430 USD for a cabled, heated ultrasonic anemometer with +/- 2% accuracy that is plug and play with a Davis VP2.
Did you receive my message?
I am sad to see your disappearing after we send you second unit ultrasonic anemometer.

Yes, I don't want to think him in a bad way.
But obviously, I was cheated and got no response after I shipped a new unit for replace to him.
All I want to do is to solve his issue, and he kept silent as if it has nothing to do with him.
Shame on him.

Anybody have any updates here? I really like the idea of the HY-WDS2DVSE but I would also like to be able to collect the detailed data. Emailed to see if I can get both outputs (I know, greedy). Anyone else try one out?
I tried the hy-wds2dvse out and ended up sending it back. I had the heated version and it worked great in snow, cold, and strong winds. The wind speed and direction were accurate. However, whenever it rained and the sensor got wet, it failed and would report 0 wind speed for 1 to 3 hours until the sensors dried off. This is a known drawback of this anemometer. I suppose if that is not a concern to you, then I would recommend this anemometer. However, I need wind data when it rains and don't want to wait a long period of time after it rains for the data to come back.
Our HY-SA3E ultrasonic anemometer is not affected by rain.

I ordered one as well.
I hope it can handle Michigan weather. I was worried about snow covering the solar panel, but the LCJ manual claims; The battery supplies sufficient voltage for 23 days without sun.

Hi Denis,
How did LCJ sensor work under snowy days? Does its battery perform in the way they said?

dendrite,
Whats the status of your testing? Should I infer from the lack of updates it's not going well?
I would like to get one of these units, with heater, if they work out as a direct replacement for the Davis anemometer in a VP2.
Had my anemometer freeze up from frozen rain again last night, it did thaw out this morning though.

Hi Denis, we have display for our ultrasonic anemometer now.
Don't need to stick with Davis now.

Stefan,
I want to "stick with Davis now" and have no interest in adding additional displays.

I also am going to stay with the Davis cup anemometer at my location due to extreme winter weather we get.
Thanks

Hi Dennis,
Sure, there is no reason to change it as long as it can meet your requirement.
By the way, how do you display realtime data in picture format in your signature?

Stefan,
As many here do, I utilize the terrific Anole's wxgraphic.php script written by Larry Boyd, now maintained by Ken True saratoga-weather.org (http://saratoga-weather.org).
Search this forum for "wxgraphic"

stefan, if you want to be successful with your products you have to make them compatible with davis systems. There are millions of davis stations around the world. People don't want to change or add other incompatible products.
