Efficient water leakage monitoring with our Leakage Monitor Flowmeter

At DHI, we have developed the Leakage Monitor Flowmeter (LMF) – a device to effectively evaluate water leakages. In doing so, water leakages can be reduced on a long-term basis. This in turn, results in direct financial savings as well as improved operation of water distribution systems.

The LMF is a ‘Clamp-On flow’ meter designed for continuous flow measurement in fully pressurised pipes. DHI CZ developed the LMF in close collaboration with German water measurement equipment specialist – NIVUS GmbH. The device is based on ultrasonic transit time method and can be installed on pressurised pipes with diameters ranging from 50-3000mm. Its long-lasting battery allows for up to three months of continuous flow monitoring. The recorded data is transferred via a General Packet Radio Service (GPRS) to the server. Here, it is analysed using the Leakage Monitor Portal. The LMF, in conjunction with the Leakage Monitor Portal, allows for fast and efficient evaluation of leakages at distribution zones of the water supply network. This in turn, provides effective solutions enabling quicker localisation of leakages.

Our Leakage Monitor Concept is a project-based solution that has been implemented for several Water Utilities over the last five years. Suitable for various water distribution networks, it assists in active leakage control and Non-Revenue Water (NRW) assessment. Moreover, it helps reduce leakage on a long-term basis. The system is managed sustainably by gathering data from the SCADA system and optimising leakage management, pipe failure detection and the associated network repair strategies.
