Topic: Another VP2 ultrasonic anemometer option

[syzygywx]

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?

Davis has a new ultrasonic anemometer partnumber 6415.
Soon available..
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.

This is the originally PDF manual brochure of the Davis Ultrasonic wind sensor...

It gives many helpful info

I just ordered one of these.

Does anyone know what "cup" setting would be used with this? (for consoles, etc.)

Large, small or other? (my RM Young uses other)

Thanks,

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).

[saratogaWX]

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.

The Davis 6415 also uses OTHER as cup size.

Thanks. I don't know if this was a "reading comprehension" issue or similar to not being able to see stuff right in front of me that the wife finds in milliseconds...

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.

[spweather]

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?

[miraculon]

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.

Ryan only had three left, when I ordered it, but it is now on backorder.

I was interested in it, but the $400+ price is a major disincentive.

Scaled Instruments lists it for $342.00.

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.

[CW2274]

Nothing like a PWS component that fails because of...wait for it...rain.

[giusCB]

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.

[wsNoordbergum]

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.

I think Dendrite dissappeared because he don't want to return extra ultrasonic anemometer we sent to him.
And the ultrasonic anemometer may never failed from the very beginning.
One more thing, I am glad to say that we have released our own display.

Thank you!
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.

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