Another VP2 ultrasonic anemometer option
« on: August 01, 2018, 07:56:49 AM »
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.

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 0C. 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.

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.
