Overview
The SPA-2 Snow Pack Analyzing System (SPA) developed by Sommer Corporation is a new type of snow water characteristic monitoring system that can continuously monitor snow water equivalent, snow density, snow depth, and ice and water content in snow. The SPA system consists of SPA sensors (also known as SWS), impedance analysis boxes, and snow depth sensors
Product Details
Developed by Sommer CorporationSPA-2Snow characteristic analyzerThe Snow Pack Analyzing System (SPA) is a new type of snow water feature monitoring system that can continuously monitor snow water equivalent, snow density, snow depth, and ice and water content in snow. The SPA system consists of SPA sensors (also known as SWS, Snow Water Sensor), impedance analysis boxes, and snow depth sensors.
Installation and measurement principles
SPA-2The station can operate autonomously (using solar energy), and the mast and frame are set in suitable positions on the horizontal ground. Climate resistant and UV resistant sensors penetrate through snow layers and use impedance analysis to measure the volume content of ice, water, and air in snow bags. Through our reliable ultrasound technologySnow depth sensor USH-8conductSnow depth measurement. Additional data storage and remote transmission equipment installed in the weather resistant control cabinet can be provided according to customer requirements.
Advantages compared to other products
· Record snow parameters: snow water equivalent（SWE）Snow density, liquid water content, ice content, and snow depth
· Energy saving operation through sleep mode is very suitable for solar measurement stations
· Single system configuration: information about complete snow cover or specific snow depth
· Record the progress of snow melting and the expected amount of water in the accumulated snow
application field
利用SPA-2The valuable information provided about snow density, liquid water content, and snow water equivalent can be used for early identification and analysis of snowmelt processes. Therefore,SPA-2The system is considered a very useful measuring instrument for hydrologists, avalanche or scientists, as well as companies operating hydroelectric power plants, flood control authorities, water supply management companies, agricultural departments, or mining companies.
