5] SCIENTIFIC \\/ WHEN MEASUREMENTS MATTER Overview The CS725 measures snow-water equivalent (SWE) by passively detecting the change in naturally occurring electromagnetic energy from the ground after it passes through snow cover. It is mounted above the ground and has no contact with the snow. As the snow pack increases, the sensor detects the attenuation of the electromagnetic energy from the ground, and SWE can be calculated. The measurement area of the CS725 is 50 to 100 square meters (540 to 1,075 square feet), making it an excellent replacement sensor for the traditional snow pillow and snow scale. Benefits and Features ) Non-contact measurement ) Excellent replacement for traditional snow-pillow sensors ) Does not cause the melt of light snow ) Greatly reduces the need for site visits ) No site preparation or earthworks required for set-up 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 For comprehensive details, visit: www.campbellsci.eu/cs725 @ [ei(fogtahi= Cs725 Snow Water Equivalent Sensor Rugged, Reliable Passive no-contact detector, ideal replacement for snow pillow Common applications for the C5725: ) Hydroelectric power forecasting and hydropower potential forecasting (Read the "Northern Canada: Hydro- electric Power Forecasting” case study.) ) Seasonal run-off management ) Flood forecasting and risk management ) Irrigation planning and management ) Performance not affected by rainfall or snowfall ) Effective with any type of snow or ice ) Will not cause snow drifting ) Seven-year maintenance cycle ) No antifreeze chemicals used (ie, glycol) (that is, liquid or frozen). A sensor installed above the ground prior to 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 datalogger or communication device via RS-232.
