The PermaNet+ Trunk Main system from HWM combines high performance Hydrophone sensor and versatile telemetry data technology to create a continuous monitoring system for sensitive pipelines.

REMOTE PROGRAMMING AND CHANGING OF ALL PARAMETERS, INCLUDING SAMPLING FREQUENCY

Once installed, leak data, calculated using the proven Permalog algorithm, and secondary data is transmitted via low cost GPRS or SMS telemetry. This removes the requirement for expensive site visits and "drive-by" data retrieval.

POTENTIAL LEAK AREAS QUICKLY IDENTIFIED

PermaNet+ TM continuously monitors noise and will auto alarm when profile or threshold alarm levels are reached. The system works in conjunction with Google Maps technology to provide a live on-screen tracking; allowing leakage teams to respond quickly to problem areas and bring them under control efficiently.

SECONDARY VALIDATION

Once the presence of a leak has been identified secondary measures can be used to check and remove 'false positives' and localize the leak position.

Correlation - Audio files are used to correlate remotely to validate that a leak is present.
Aqualog - remotely retrieving the Aqualog detailed noise graphic, clearly indicates the consistent presence of a leak.
Audio - For operators who prefer to 'hear' their leaks audio files are transferred to the host.
