permaNet+

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.

     KEY BENEFITS

■ Remote notification of leak,reduces leak run
time
■ No above ground infrastructure,all deployed
below ground
■ Secondary validation:
Audio-remotely listen to the noise
Remote correlation to verify leak present
Aqualg-detailed noise histogram
to reduce 'false positives'
Leak sizes can be determined by matching
daily alarms with flow data to enable leak
alerts to be prioritised.
■ Processing via server hosted software,map
based ALMOS web viewer
■ Ability to log noise more frequently to
establish the noise profile and profile alarms
for precise immediate leakage alarms
■Problem zones brought quickly and
effectively under control.
■ External antennas to improve signal strength.
■ Fully sealed & submersible,IP68.
■ small low cost communication module
■ Designed with latest mobile technology to
maximise dial in and minimise cost.
■ All parameters programmable from host
■ Can be deployed semi-permanently
withequipment easily moved and deployed in
alternate chamber
The PermaNet system from HWM combines Permalog
leak noise sensor,and versatile telemetry data
technology,with Aqualog and Correlation secondary
validation, to create an advanced fixed network to
monitor leakage.
All components are deployed in the chamber,removing
the need for expensive and disruptive above ground
installations.

Remote programming and changing of all parameters,
including sampling frequency.

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
map based system provides live on screen tracking.
allowing leakage teams to respond quickly to problem
areas.
Secondary Validation
Once the presence of a leak has been indentified,
secondary measures can be used to check and remove
'false positives'before teams are deployed.
■ 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.

Users of the PermaNet system simply have to visit the ALMOS LEAK website,log in and can then see the
precise location,condition and noise levels of the PermaNet installations either in list form or overlaid onto
a map of the area.
In map view,loggers in a 'normal'stat

eappear as a blue dot, those with a leak

appear with a red one and those with

anomalous readings have a yellow warning sign.

 
Any of these points can be clicked on to get more detailed information about the logger,including serial number,noise level and signal strength.This allows both instant and exact identification of problem areas.

Secondary validation modes,confirm a leak presence and avoid false positive before crews are deployed.

permalog®

Permalog® enables water suppliers to quickly and efficiently locate leaks in the water network. Loggers are deployed in areas of the distribution system to provide continuous monitoring of leakage. Easily installed on pipe fittings, they are retained in place by a strong magnet and are powered by low cost replaceable batteries. As soon as a potential leak is detected, the Permalog® unit enters an alarm state and transmits a radio signal to indicate a "LEAK" condition.

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 leak and non leak noise. The highly versatile logger has user changeable plastic/metallic alarm threshold settings and allows data to be accessed via:

 •  Lift and Shift – loggers are removed from the ground and the data is manually retrieved
 •  Patroller "Drive By" - data is transmitted via radio to a moving patrol vehicle using a Patroller system       
 •  PermaNet – data is transmitted directly to an office computer via radio network or SMS repeater.
