- Automatic up to date measurement of snow load on roofs
- Increase of building protection
- Realistic and high representativness of the current snow load on roofs through
- Minimization of ice bridging effect
- Optimized heat flow between sensor and roof
- Perfect adaption to the roof because of the flat design of the snow scale
- Light operating weight (110 kg = 16,5 kg/m² measuring surface)
- Customized resolution - 3 different measuring ranges depending on maximum roof load
- Simple and easy installation and setup
- Simple systems integration
- No slack flow because of perforated plates
The SSR Snow Scale is a measuring device which has been developed for measuring the snow load on roofs. The SSR is the result of years of research for this purpose of measurement. Especially the changes in the norm of snow load in middle Europe and the increase of snow amount during the last years had been the reasons for Sommer to develop a new system for snow load measurment on roofs. The snow scale SSR provide the opportunity for dircet monitoring of the current amount of snow. Therefore the snow scale is a perfect decision guidance in load case and contributes in the area of building security.
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 use the snow scales accordingly. In comparison with the commonly used snow pillow, the snow scales does not use antifreeze and therefore can be installed in natural reserves without any risk.
The working principle of the SSG is based on the measuring principle of load cells. The sensor consists of seven perforated panels of 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 centre plate, the surrounding plates serve as a stabilizing zone in order to compensate stress in the snow pack as well as to counteract the problem of ice bridges through the large measuring surface. The SSG system provides more accurate measuring data compared to the snow pillow during periods of snow melt. Furthermore, the modular design of the snow scale facilitates quick and easy assembly on level ground up to an inclination of five degrees.
