Rain Funnel coil spring/filter

Q. What is this coil spring that came with my rain gauge?


It is a stainless steel filter which is included in the package. It’s aimed to stop leaves or bird droppings to avoid the obstruction of the cone hole.

The installation is simple: press the filter until the hook is inside the outlet hole and self -locked. The spring tension will keep the filter sit tight on the funnel.
