Introduction
Thank you for choosing an HWM data device, we trust it will provide you with many
years of service.
This manual has been written using the PermaNetPlus version 2.41 and
PermaNetPlus LLC version 3.11, and as such the figures may look different to your
installation.
Overview
Pipeline leaks are a constant burden to water and gas industries, which can affect
the efficiency of the individual company’s performance. As well as reducing the
amount actually being delivered, leaks also impact the financial side of the business,
and the longer the leak is left, the larger the economic, and potentially
environmental, consequences. It is therefore safer and more beneficial to detect a
leak and repair the damage to the pipes before it causes more damage to the
business. At HWM, we pride ourselves in designing the best leak detection
equipment at an affordable price for the benefit of the water and gas companies.
Our Permalog+ product family (yellow) aims to detect when a leak is found, and it
has successfully done so for the last ten years of service. The Permalogs are
functioning microphones that can detect the sounds emitted from a potential leak.
To conserve battery life and increase their life expectancy, the loggers take one
reading every 24 hours, and once deployed, the Permalogs can be programmed and
read locally through radio communications.
Our SoundSens and Aqualog product ranges record the sounds detected along the
pipeline and correlate them to determine where the leak is located. They have
successfully detected leaks with a high accuracy, and helped companies find and
repair leaking pipes. In the past, these products were used when there may have
been leaks in pipes.
Our new PCorr+ system (Blue) combines the Permalog+ family with the SoundSens
and Aqualog products to not only detect, but also localise the leak. By combining
these products, the amount of hardware required for leak detection and localisation
is reduced.
The software has also been combined to deliver fast readouts from the loggers, and
also determine the location of the leak. With the new software you will be able to:
 Determine whether a leak has been detected,
 Configure the loggers to read and record sound data at a specified time,
 View a map of the locations of the loggers,
 Correlate the recorded sounds to determine a location of the leak, and
 Analyse the sound recordings manually.
This document has been produced to help guide you through the features available
within this powerful software. Please read through this manual to understand how
the software works. Should you have any questions that are not covered by this
manual or FAQs provided online, please contact the HWM Technical Support team on
