Reservoir in the Alps – level measurement with autonomous power supply
In a current project, a natural alpine lake is being expanded and converted into a reservoir. The construction site, located at nearly 2,500 meters above sea level, has to be protected against flooding. To accomplish this, the level of the lake is constantly monitored during filling. The level rises sharply especially in the spring, when the snow melts. But how do you monitor the level of a reservoir in the middle of the Alps, where there is no electricity and no direct road access?
|Medium||Melt and rain water|
|Medium temperature||+4 .... +12 °C|
|Measuring range||50 m|
|Ambient temperature||-20 ... +40 °C|
The water level in the reservoir is reliably detected and sent over the air to a VEGA web portal. The control centre of the utility company accesses the portal via a client-server connection and makes the readings available in its own network. This ensures uninterrupted monitoring around the clock. The entire solution is so energy efficient that it is able to make do with a small solar panel. An accumulator stores the energy captured from the sun.
The measuring system is thus independent of an external power supply and, thanks to its integrated power management system, can be operated over long periods of time.
- Reliable level measurement in the reservoir secures the construction site
- utonomous measuring system, no additional power supply required
- Current measurement data readily available via radio modem in control centre
