The SnowPackAnalyser measures the volumetric contents of ice, water and air together with the snow depth and calculates the SWE and the snow density. Features and advantages 9 Recording of the snow parameters • snow depth • snow water equivalent (SWE) • snow density • liquid water content • ice content 9 Sensor integration via RS 485 or SDI-12 interface 9 Energy-saving sensor operation • sleep mode between the measuring intervals • ideal for solar-powered stations 9 Comfortable parametrisation 9 Information about SWE, snow density, liquid water and ice content • of the whole snow pack • of specific snow layers

Introduction Automatic and continuous measurement To measure certain snow parameters can be a challenging task. Therefore, several different variables have to be measured to be able to provide reliable information about the whole snow pack. In addition, snow has a considerable variability in space and time. Until now, only punctual measurements for certain values were possible. With its strap sensors and different system assembly versions the Snow-PackAnalyser System (SPA) now constitutes a revolutionary innovation for an automatic, continuous, and most Measuring principle Snow depth The measurement...

The SPA-system can be operated with up to four SPA sensors. Their quantity and system assembly depends on the different and individual measurement tasks. The SPA is installed on the ground resulting in the sensors to be stretched horizontally or slopingly in the snow Combination (horizontal/sloping) This version combines a sloping with a horizontal SPA sensor. The sloping one determines the parameters SWE, snow density and the liquid water and ice content across the whole snow pack. The horizontal sensor strap provides important data about the snow pack near to the ground, for example the snow...
