The Rain Gauge measures the amount of rain, snow or hail that falls on the ground. It functions as a “tipping bucket”: the water passes through the funnel and is collected by a calibrated bucket. After a pre-set amount of precipitation, the bucket tips over, and automatically sends a signal to an external data acquisition system.
The design of the rain gauge prevents rain from splashing in and out, as recommended by the World Meteorological Organization.
A protection filter prevents leaves from falling inside the collector. The shape and size of the filter are designed to reduce possible clogging.
The optional heating system makes sure snow or hail can be measured as well, while preventing evaporation of the water.
