Technical Description

The CS725 uses an innovative, non-contact method of measuring snow water equivalent (SWE). It passively detects the change in naturally occurring electromagnetic energy (mainly from the decay of “°K) from the ground afterit passes through snow cover.

As SWE changes, the amount of energy that penetrates the snow pack changes—regardless of the state of the water (that is, liquid or frozen). A sensor installed above the ground priotro the first snowfall will have a base-line measurement of the electromagnetic energy coming from the ground. As snow accumulates and energy is attenuated, the SWE value will increase. The CS725 has an internal processor that determines the SWE and sends this information to a dataloggeorr communication device via RS-232.
