Snow Scales SSG-2:
Continuous measurement of the snow-water-equivalent (SWE)
The snow scales SSG-2 are a measuring device that measures the snow water equivalent (SWE) of the snowpack with a high level of precision and reliability. The installation is quick and easy. The fact that no antifreeze is needed makes the system environmentally friendly.
Fields of application
The snow water equivalent serves as an important parameter in monitoring snow and rainfall and in assessing snow quantities, as well as for flood protection or water management. Various environmental authorities, weather services, hydrologists, and water management organizations use the snow scales accordingly. In comparison with the commonly used snow pillow, the snow scales do not use antifreeze and therefore can be installed in natural reserves without any risk.
Implementation
The working principle of the SSG-2 is based on the measuring principle of load cells. The sensor consists of seven perforated panels with a size of 80 x 120 cm each. This makes a total measuring surface of 2.8 x 2.4 m. The perforation of the panels prevents water accumulation, minimizes the difference in temperature between the scales and the ground, and promotes uniform melting. The measurement is carried out on the center plate, and the surrounding plates serve as a stabilizing zone in order to compensate for stress in the snowpack as well as counteract the problem of ice bridges through the large measuring surface. The SSG-2 system provides more accurate measuring data compared to the snow pillow during periods of snowmelt. Furthermore, the modular design of the snow scale facilitates quick and easy assembly on the level ground up to an inclination of five degrees.
