Sommer SPA-2 Snøanalyserer

Sommer SPA-2 Snow Pack Analyzer registrerer automatisk og kontinuerlig alle viktige parametere i en snøpakke og kan samtidig bidra med å forutsi snøsmelting. Lavt strømforbruk og dvalemodus gjør den ideell for bruk på avsidesliggende lokaliteter uten fast strømforsyning.

  • Den nye generasjonen SPA-2 tilbyr et meget brukervennlig grensesnitt
  • Standardisert datautgang via RS-485 eller SDI-12
  • Måler snøvannekvivalent (SWE), snøtetthet, flytende vanninnhold, isinnhold og snødybde

Description

The SPA system records automatically and continuously all important parameters of the snow pack 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 analogue sensors has become a lot easier and the new standard for data outputs is realised via a RS 485 or SDI-12 interface.

Features and Advantages
  • Records several snow parameters: snow water equivalent (SWE), snow density, liquid water content, ice content and snow depth
  • Energy-saving operation through sleep modus, ideal for solar-powered measuring stations
  • Individual system configuration: information regarding the complete snow pack or about specific snow profile depths
  • Recording the progress of snowmelt and the expected quantities of water from the snow pack
Fields of Application

With the valuable information from the SPA 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 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.

Implementation

The SPA 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 the 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.
