Measuring The Snow Pack Parameters With The Spa-2

The SPA-2 system is a powerful tool for recording all important parameters of the snowpack. It allows for the automatic and continuous measurement of snow parameters, including snow water equivalent (SWE), snow density, liquid water content, ice content, and snow depth. This information is essential for recognizing and analyzing the snow-melting processes at an early stage.

Features and advantages

Automatically records the snow parameters for detailed analysis Energy-efficient operation through sleep mode, perfect for solar-powered measuring stations Customizable system configuration for complete snow pack or specific snow profile depths Measures the progress of snowmelt and predicts the water quantities from the snowpack

Fields Of Application

The SPA-2 system is widely used by hydrologists, avalanche warning services, scientists, companies operating hydropower stations, flood protection authorities, businesses in water management, the agricultural sector, and mining companies. The information provided by the SPA-2 about snow density, liquid water content, and snow water equivalent makes it a valuable measuring instrument.

Installation and measuring principle

The SPA-2 station can be operated autonomously using solar power, and the mast and frame are set up 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 the reliable ultrasonic snow depth sensor USH-8. Additional data storage and remote transmission equipment can be provided in a weatherproof control cabinet upon request. With its user-friendly control interface, connecting analogue sensors has become easier, and data outputs are now available via RS 485 or SDI-12 interface.
