Does anyone have something comparison of cup/turbine anemometer?
Is its worth replacing the turbine version?
I have WS2307 (yes, it is an old model, but tx20 cup style is still available) and I would like to replace the wind meter to cup.
I think my station is very good and accurate now, except anemometer. La Crosse doesn't have new and better stations now (The 2800 series has 17 sec interval with measuring wind speed!), Peet Bros/Davis are too expensive and Fine Offset stations have 48 sec interval with wind...
So, I think it would be best to upgrade the anemometer.
A little late but I just discovered this. May help for the time you have to wait for the cup type replacement.
I removed, cleaned, oiled (with machine oil)
the 2 bearings on the fan axle (see bottom image) and got this result from the anemometer. The cup type (ws2810) is mounted right next to it for comparison.
