THEORY OF OPERATION:
The RGS - 100 has no moving parts, so it NEVER needs routine calibration. Its revolutionary patented design enables it to make accurate measurements from 0 mm to 300 mm (0 " to 11.8") of rainfall per hour.

The principle is simple. Water, collected by the funnel, is routed to the measuring chamber. A solid-state level sensor, connected to an electronic circuit, outputs a contact closure for every 0.2 mm (or 0.01" depending on calibration). When 1.2 mm (or 0.06") of water is collected, it is siphoned out on to the ground. The process repeats indefinitely. The siphoning action takes approximately 1 second. The electronics filters out false readings, therefore the gauge is very precise. The RGS - 100 can be connected to the "contact closure" input of any weather recorder.
