HWM's WebCorr is a mobile application that delivers rapid in-field correlation of data collected by PCorr+ data loggers.

Requiring no internet connection or DataGate account, WebCorr uses wireless connectivity to retrieve data (via Patroller 4) and quickly provides correlation of leak noise to effectively locate leaks.

WebCorr's software features full analysis, including upload of sound files and the ability to request sound recordings from deployed loggers.  When combined with the correlation feature of the App, this allows the user to locate leaks on site.

WebCorr can also be used to view data gathered from Permalog+ devices.

For customer with DataGate accounts, additional Web-enabled features are available through connectivity to PermaNET Web.



In ‘stand-alone’ mode, WebCorr can be used to configure PCorr+ and Permlog+ data loggers, listen to sound files recorded by PCorr+ devices and correlate recordings with results delivered in graph format.

The built-in Manual Intelligent Filter System (MIFS) provides a variety of different Band Filter options, helping users to quickly and accurately locate leaks.

Additional features available through connectivity with PermaNET Web include DMA clusters, GIS integration, leak ranking, installation database, communications monitoring and full remote re-programming.
