The Enigma3m correlating noise loggers utilise 3G / GPRS communications to provide remote location of leaks in water distribution networks. Enigma3m is deployed in underground chambers and requires no costly above ground technology.
The Enigma3m correlating loggers transmit daily leak noise data via the 3G or GPRS communication networks. This data is sent to a server. The data provides leak alarms and also enables the user an opportunity to listen to the noise thus helping to confirm it is leak noise. Furthermore, correlation can be performed from many loggers to accurately locate leak positions. To enable accurate correlations a daily logger time synchronisation is carried out.
PrimeWeb provides a database and online viewing facility for network flow, pressure and leak alarms from XiLog+ data loggers, Phocus3/3m noise loggers and Enigma3m /3hyQ correlating noise loggers. It is accessible on any device with internet access. Logger positions can be shown on Google Maps* and coded to show leak alarms. Historical data is also available. Indication of leak positions on Google Maps* together with ‘street view’ visualisation of the leak position aids management for leakage teams.
“I believe this is the biggest step forward for leakage management we've seen in well over a decade. It's a potential game changer, as I am doing some work on background leakage and problem DMAs - many of the areas with high background leakage also tend to be the most costly to manage or have high leakage above policy min. What we have is something that for me is going to change the economics of leakage management – but needs to be deployed where the most gains can be had. A blanket approach probably won't do it.” Glen P. Mountfort Leakage Strategy South Staffs Water
