Progress in Technology to Detect and Locate Leaks

In the fight against unnecessary and costly water leakage, technology is
almost certainly the most effective weapon at our disposal. Several recent and emerging developments are showing a great deal of promise in not only winning the war, but by actually changing the way in which it is fought.
PermaNet from Halma Water Management (UK) is a new system designed to provide a constant and inescapable net to catch leaks in a water network. After installing permanent Permalog+ dataloggers along with PermaNet transmitters at various points throughout the network,
notifications about leak location and size can be immediately sent to a
central computer for exceptional response times and efficiency.
Once the local area has been identified, the new MicroCALL+ digital correlator takes the guesswork out of pinpointing the leak. A complete array of preset filters work with three outstation measurement and automatic velocity verification to provide highly accurate readings regardless of pipe type. This easy efficiency reduces the incidence of `dry holes` and speeds up the process of leak finding.
