New water leak detection system offers secondary validation through correlation and remote listening

Posted: Monday 12th January 2015

Water and asset monitoring specialist HWM has added secondary validation to its PermaNet leak detection system. Once a leak has been identified, the new PermaNet+ gives operators three secondary options to check for false positives prior to team deployment: remote correlation, remote retrieval of a detailed Aqualog noise graphic or listening to an audio file transferred to the host PC.

Every component of the PermaNet+ system is installed in the chamber, removing the need for expensive and disruptive above-ground installations. With multiple secondary validation options, false positives are reduced and efficiency increased as teams are sent only to validated leak locations.

PermaNet+ allows leakage teams to monitor the live status of each deployed logger on map-based software from any internet-enabled device and respond quickly to problem areas.

The unit is fully remotely programmable, including the ability to change sampling times and intervals. More frequent “continuous” sampling means the system can be used to permanently monitor sensitive pipelines, with the potential to acoustically check for leaks every 15 minutes, if required. A range of external battery boxes are available to support this continuous sampling mode of operation.

Permanet+ is supplied in a smaller unit than its predecessor. The product is fully sealed, submersible and rated IP68.
