Leak detection for district heating

Description
Leak detection for district heating is an important element to maintain pipelines as they are prone to leakages and digging damages. Without continuous remote monitoring these faults are not detected in time. With this remote monitoring solution asset owners can monitor their pipelines in real-time.

Why leak detection devices?

-Direct detection of excavation damage

-Continuous monitoring of pipes during warranty period (and beyond)

-Savings of operational man-hours

-Reduced administrative burden (direct and automatic historical measurement reports incl. audit trail)

-Extended lifetime of pipes

-Less serious damages and lower damage costs

Specifications

The leak detection remote monitoring devices come in two different versions. One is mains powered and can be installed in substations or anywhere where there is 230V. The advantage being that the measurement frequency can be much higher. There is also a battery powered version which can be installed in substations where there is no mains power or in test posts.
