PermaNet+ GPRS/4G enabled Correlating Leak Noise Logger

PermaNet+ GPRS/4G enabled Correlating Leak Noise Logger

PermaNet+ GPRS/4G enabled Correlating Leak Noise Logger is a Fixed Network Buried Water Pipe Leak detection system that combines a leak noise sensor with versatile telemetry technology for creating a fixed network to monitor leakage in buried water pipes.

PermaNET+ based on fixed network telemetry for 24X7 leak monitoring of buried water pipes provides a GIS based monitoring system allowing real time monitoring by central office or leak detection teams. The PermaNET + installed usually as multiple units for creating a fixed leak detection network detection system, employs a specialized microphone that monitors & detects sound waves created by escaping water from a leaking buried water pipe, measuring the noise levels once per day and performs statistics analysis to generate data for a “noise histogram”.

Typically, ≥ 20 loggers are recommended to be installed within an area keeping distance upto 200 meters between loggers when installed on a metal pipe & upto 50 meters when installed on plastic pipes.

The leak noise sensor loggers can be programmed to switch on at a given time in a night or day for noise sampling. The device listening for possible leaks analyses & determines Leak /No Leak and in case of a suspected leak, based on built in algorithms, goes into an alarm mode, alerting the water department team, while recording the leak noise sound.

Sound and data files recordings in the logger are automatically sent over the internet to the DataGATE server, and accessible through the PermaNET web application. Additionally, the leak detection team can view daily Histograms of individual loggers, or via detailed Aqua scans including 3D views.

PermaNET+ is also compatible with google maps & allows overlay allowing leakage teams to monitor each deployed logger’s status via Google Maps compatible software.

Built in Telemetry & GIS Mapping: Equipped with an integral modem supporting GPRS/2G, 4G, LTE-M (Cat-1), with an external GPRS antenna. PermaNET+ operates on low cost cellular data transmission to the DataGate server. In such a case that data transmission is unavailable, it falls back to 2G based on sim card which is slotted into the system, in which case an SMS with Logger ID is included as a message to the user advising a potential leak. With the Built in 2 way UDP communication, it is also possible to remotely reprogram the logger.

Antenna options for LTE 4G connectivity: Antennas for cellular GPRS data transmission is selected or advised based on chamber construction, and is installed as close to the surface as possible. Antenna options include:

1. Carant Type (Subsurface Chambers)
2. I-Bar (for attaching to structures external to subsurface chambers)
3. Button (drilled into chambers manhole / lids).
