The PermaNet system from HWM combines Permalog leak noise sensor and our versatile telemetry data technology to create a fixed network to monitor leakage.
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.
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 life on screen tracking, allowing leakage teams to respond quickly to problem areas and bring them under control efficiently
Once the presence of a leak has been identified, secondary measures can be used to check and remove
‘false positives’ and also to localize the leak position.
Correlation – Audio files are used to correlate remotely to localize 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.
