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.
