RECORDING ALL IMPORTANT PARAMETERS OF THE SNOWPACK

The SPA-2 system records automatically and continuously all important parameters of the snowpack and allows, for example, for predictions about the snow melting progress. The latest product generation, the SPA-2, now offers a completely new and much more user-friendly control interface, connecting analog sensors has become a lot easier and the new standard for data outputs is realized via a RS 485 or SDI-12 interface.

FIELDS OF APPLICATION

With the valuable information from the SPA-2 about snow density, liquid water content and snow water equivalent it is possible to recognize and analyze the snow melting processes at an early stage. That is why the SPA-2 system is considered to be a very helpful measuring instrument for hydrologists, avalanche warning services or scientists as well as for companies operating hydropower stations, flood protection authorities, businesses in water management, the agricultural sector or mining companies.

INSTALLATION AND MEASURING PRINCIPLE

The SPA-2 station can be operated autonomously (using solar power), the mast and the frame are set up in a suitable position on level ground. The weather and UV-resistant sensor band penetrates the snow and measures the volumetric content of ice, water and air in the snow pack using impedance analysis. The snow depth measurements are taken by our reliable ultrasonic snow depth sensor USH-8. Data storage and remote transmission equipment mounted in a weatherproof control cabinet can be provided additionally upon customer’s request.
