Area's of application


Hydreka has developed equipment designed to monitor drinking water networks. In 2000, Hydreka absorbed Metravib Fluide, thus becoming part of the Halma Group. 

surface water

Surface water is where raw water sampling is carried out and where discharges are dumped. They therefore require quantitative and qualitative monitoring.
Hydreka offers portable as well as fixed-installation measuring systems to monitor such things as river levels with GSM communication mode (warning station).

ground water

Particular attention should be paid to hidden raw water resources. Hydreka has a range of measuring systems to monitor water table levels, carry out spot checks on the speed of subterranean streams and monitor bore hole outflows.

waste water


HYDREKA has developed a range of solutions to monitor sewage and wastewater. These measuring systems can be used to measure depth, flow in open channels and pressurized pipes, sampling, physico-chemical quality assessments and rainfall.
Each measuring system is available in portable version or as a fixed installation.
