what is this coil spring for?
« on: May 21, 2020, 07:56:28 AM »
Hi, brand new to this forum.
I read quite a few posts here and decided on the Ecowitt GW1002. Setup was very easy and I'm getting data. However, looking in the box I found a coil of wire. It's not mentioned in the parts list. Does this belong somewhere?

You put it in the rain funnel. It is to help keep leaves and other stuff from affecting the rain gauge.

Added the WH40 rain gauge to my WS-2000 and WS2902a.

In a very light rain Im thinking it too spring filter might be too restrictive.

The rain gauge on my array registered .04" of rain, the WH40 registered 0" of rain. Thinking of not using the filter spring.

there are many studies on the sieve to be used in the collection cone of a rain gauge
the primary objective is to retain leaves carried by the wind, bird droppings, parts of branches, pollen balls and everything that does not have to reach the internal measurement system, while allowing water to pass
unfortunately, however, the molecular properties of water, the phenomena of adhesion, cohesion, capillarity etc. come into play
the filter adopted by ecowitt is effective but can certainly cause in some cases an underestimation of rainfall, just observe its conformation
in weak rain conditions but with very weak ventilation (vertical precipitation) I have not noticed any worsening compared to the use without filter
