PCorr+ builds on the proven reputation of the Permalog leak noise logger but brings new advanced features:

  • Flexible deployment – permanent, semi-permanent, or ‘lift & shift’
  • Remote listening mode
  • Correlation mode
  • Auto download of 1 month history

PCorr+ enables water suppliers to quickly and efficiently locate leaks in the water network. Loggers are deployed in areas of the distribution system to provide continuous monitoring of leakage. Easily installed on pipe fittings, they are retained in place by a strong magnet.  As soon as a potential leak is detected, the unit enters an alarm state and transmits a radio signal to indicate a "LEAK" condition. 

When a leak is identified, the unit automatically records the noise for radio download correlation and sound file listening. Water suppliers can monitor 100% of their distribution system confidently and effectively, enabling leakage to be reduced quickly, and easily maintained at a low level. 

The new Patroller 4 features a small low cost USB radio receiver designed to be used with tablets or other compatible devices running the PCorr+ software.

PCorr+ software provides map based displays and all functionality for:

Multiple operating modes

  • Drive-by
  • ‘Lift and Shift’

Multiple functionality

  • Leak alarms
  • Noise data and history

Lift and Shift Data Collection

The PCorr+ “lift and shift” mode is designed for use in a rapid deployment mode allowing users to distribute loggers into the distribution systems, quickly identify potential areas of leakage and then re-deploy the loggers into another area.

Drive By (Patroller 4) Data Collection

PCorr+ has an improved surveying speed enabling fast radio download of new data, including full noise logging Aqualog graphics where further investigation is required. The drive by version   features a new PDA based bluetooth Patroller (Patroller 4) to enable remote multiple logger programming and download.
