The effectiveness of Permalog® technology has been proven again and again in some of the harshest conditions on earth. Loggers are immersion-tested to IP68 and will continue to operate even in flooded chambers. 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 Permalog+ includes Aqualog extended logging functionality, where noise is recorded at preset intervals over an extended period of time. The logger can store up to twenty-nine days of level and spread history and the noise trends identified can then be presented in graph format, enabling the user to distinguish clearly between a leak and non-leak noise. The highly versatile logger has user changeable plastic/metallic alarm threshold settings and allows data to be accessed via:

Patroller “Drive By” - data is transmitted via radio to a moving patrol vehicle using a Patroller system

KEY FEATURES

• Flexible deployment options – permanent, semi-permanent or survey (as required by area)
• Responds rapidly to new mains bursts, improving service to customers
• Automates leak surveying, eliminating human error and finding leaks that would otherwise be missed
• Completely non-invasive method with no detrimental effects on supply to consumers
• Loggers can be quickly deployed and used repeatedly with no disruption to the surrounding area.
• Low cost battery replacement and rugged construction enable long term low leakage levels to be maintained easily with minimum maintenance.
