Level monitoring at reservoir in 2474 m altitude

Sleep Control operates energy self-sufficient application

That’s why a small solar panel and a small accumulator set for buffering the harvested energy is sufficient for the whole measuring station.

We call this Green Efficiency!


  • Enables energy self-sufficient applications

  • Monitor level and other operating parameters

  • Dispatch fault messages

  • Cascade alarm messages

“Linthal 2015” is an underground pumped-storage power station in the Swiss Alps. Water is pumped back from the Limmernsee into the Muttsee, that is located 630 m above, and used for power generation. The pump and turbine capacity of 1000 MW each can substitute a nuclear power plant.
