The engagement surface rain gauge VP2 and their calibration.

Hello,
Does anyone know what is the catch area for VP2 bucket?
I’m not sure setting a shuttle from the manufacturer because one side is turned upside down when 2.9mll and other party at 4.6mll water.
Just this setting results in a deterioration of rainfall.
How many milliliters of water in zkutečnosti has flip the shuttle.

214 cm2 (from the Davis specification).

That is more than two meters!
Are you sure that this is so?

You asked for the area, that is the area in square centimeters.

Hmmm, maybe your browser didn’t show the 2 in cm2 :?

The browser is fine, but 214 cm2 is 2.1 meters which is weird, maybe I can not count :smiley:

Aint it 856?

214cm2 is 2.14m2
so something not right there, lol
214mm2?

Nope! You divide cm by 100 to get metres. You divide square cm by 100*100 = 10,000 to get square meters :wink:

yup, you are right
I should have known that
(I asked my daughter, but she got it wrong too)

:lol:

I found this at our forum.
J question whether the area 214 or 240 cm2

I’ll be more on the subject in 2010. Did the calibration raingauge Davis Vantage Pro 2 I count all the newly found and that your calibration and instructions were not very inaccurate. Begin by order. We know that the engagement surface raingauge Davis 240 cm2 precisely 240.52 cm2. First, calculate the how much should be “ml” of water to reach 1 mm of precipitation relative to the catchment area of ​​240.52 square centimeters. Radius receiving area raingauge is 8.75 cm, so we’ll have some v

Just measure it. The diameter would have to be 1 cm bigger than the specification for the area to be 240 cm2.
