THEORY OF OPERATION:
 The RGS – 100HL has no moving parts, so it NEVER needs routine calibration. Its revolutionary design enables it to make accurate measurements from 0 mm to 500 mm (0 " to 19.7") of rainfall or 0 to 5.0 liters of water flow 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 (2.0 ml volume of water flow). When 1.2 mm (12 ml) of water is collected, it is siphoned out on to the ground. The process repeats indefinitely. Because the siphoning action takes approximately 1 second, and the electronics filters out false readings, the gauge is very precise. The RGS – 100HL can be connected to the contact closure input of any weather recorder.
