Leak detection

Detailed water flow detection

With laser-based fibre optic technology, physical parameters can be measured in a detailed grid. Temperature changes, an excellent indicator for water flow, can be monitored continuously and accurately every meter over long distances. This is an approved method for leakage detection along dikes and dams.

With detailed temperature measurements, also the ground water flow through a soil or sediment layer can be continuously monitored. This can be used for monitoring the watertightness of a sediment cap for a contaminated soil layer.
