If you like you can follow my ws80 vs wh31 in a Barani Meteoshield Standard comparision at this link

I have read all your comments with interest and promise to keep the community advised of what I see having the benefit of both bits of kit especially with rain in mind.
I am sure Mauro in Italy will also as he has the benefit of a VP2 to compare with as well.

The transducers seem to be well recessed (see previous photo) and on the top of the sensor housing so I hope this might help on the rain droplet issue.

As for build quality, I don't disagree that there is a risk for anything mass produced at a cost point that you will get build issues, but in general I think the fine offset kit has come on leaps and bounds over the last 5 years in terms of technical design and quality of product. They also seem to be genuinely interested in what the community say about their products and keen to improve them when something is observed. Not many companies seem that invested these days and I know that they are developing all sorts of nice technology for the PWS market.

I agree, and you can be sure, I will post every positive or negative impression without filters
from yesterday I've turned the ws80 sensor to North, same exposition of vp2 and same height of vp2 anemometer
Ecowitt staff has my tests to learn what is good and what is wrong, and I think nobody low end company can have same attention, this is a very great value in my opinion
I cannot ask them to test the ws80 on water triple point, this is not a professional sensor factory

Actually we made a lot test inside a high raining intensity simulation chamber and we can confirm that this rain water accumulation on sensor issue is not a problem with our design. I have this installed on roof through a typhoon with heavy rain , all the readings seams normal. We would like more testing result from you guys to see if there are problems there. Thanks for all the efforts and help.

Thank you Henry, that's very positive information and good to hear!
Hopefully our real world observations will follow your Typhoon testing and lab work.
Mind you I really don't want to see anything as extreme as a typhoon here!

Yesterday we have had a very powerful thunderstorm, with downburst, lightning, and thunders
from the start of this event, the ws80 wind sensor show this:?

Can you show a graph of the wind direction?

if I understood well, you can confirm same problem?
so, the ultrasonic wind sensor inside the ws80 is absolutely not good in very strong environmental situations?
this is not a good news

just as i thought wind sensor fails or becomes erratic under intense rain ,your chart vento see it straight line for almost length of rain event or did it dry it out and come back to life .. now anyone sez to me these are or its more accurate than a traditional cup design or comparable go and wait for an intense rain event like this guy just had ,then make that quotation..this replicates what i had seen using an ultrasonic sensor for last two years . low end consumer versions like these or weatherflow versions are inconsistent during
adverse conditions , no point in having sensitive at low end speeds when it cant meet the needs when things go a bit wild on the weather side of things.. another unconvincing attempt at this technology.

I don't have the WS-80 but I can confirm that the same thing happened to two different models of ultrasonic anemometer I owned.

just to throw in for fun the use of piezoelectric sensors , we had three earth tremors this morning one deemed as an earthquake at 4.9 all recorded rainfall using a piezo sensors . epicenter was 30km aprox from home..
thing im saying piezo types be it wind or rain are prone to so many adverse things involving sound and vibrations ,water..  piezo sensors make good low cost acoustic guitar pickups ...

ps you can replicate wind sensor issue when wet by just getting your garden hose out and spray on the wind device for 10 minutes or so...

Heavy thunderstorm rain is like every other day occurrence here in central Florida in the Summer. No thanks, I'll keep my wind cups and vane.

Oh dear that's disappointing to see.
Here in the southern UK former Tropical storm Humbert blew through in the early hours with heavy rain and thunder. I expected to see some sort of impact on the sensor but it all looked ok.

Only a question, 26,4 mm is the maximum rain rate?
thanks

Yep, 26.4 was the peak rain rate....OK, so not massively heavy but fairly heavy rain for my location.
I think we topped out at 26.7 mm of rainfall which is a lot for a few hours when the annual rainfall is approx. 400mm here.

That would have been torrential. My Davis recorded 75mm/hr this morning but the Ecowitt was only 16.2mm/hr during torrential rain. Davis calculates the rain rate extremely fast and it always tallies up with the rainfall radar return echoes. The Ecowitt calculates it a different way, so it will never match the Davis.

ok, just for clarify, I have my ws80 from about two months, we have had some good rainy days, and without problems of ws80 wind measurements but not with same yesterday rain rate :)

we had a very powerful rain downburst, with thunder and lightning in the proximity, my davis vantage pro 2 yesterday rain rate
