The PermaNet system from HWM combines Permalog leak noise sensor and our versatile telemetry data technology to create a fixed network to monitor leakage.

REMOTE PROGRAMMING AND CHANGING OFF 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+ allows leakage teams to monitor the status of each logger deployed from map based host software any internet enabled device using ALMOS LEAK. 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 also to localise the leak position.

Correlation - Audio files are used to correlate remotely to localise the leak position for follow up
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.
