The sound recording can be up to 20 seconds in duration. It can be made automatically
when the logger encounters a new suspected leak. The sound file can be downloaded
from the device and used to confirm whether the sound from within the pipe does
resemble the sound produced by a leak.
PCorr+ products can, when several units are used together, be used to approximately
locate the position of a leak. This is an advanced use of the product. Always use a
ground microphone to confirm the leak location prior to commencing repair works.
Note: Many
of the logger’s activities occur at specific times, according to the
configuration programmed into them.
The logger itself makes no automatic annual adjustments to its clock-time
(e.g. for daylight saving).
If it is required to change the time within the logger to match any local time
changes, this must be done by reprogramming the devices with the changed
clock-time.

The logger devices form only a part of a functioning system; other items are required.
A typical system will comprise of:
•
A set of loggers (PCorr+ or P).
These typically are set to evaluate the sounds within a pipe overnight, when
water use is minimal, and determine if a leak could be present nearby.
•
A Patroller unit.
This is required to communicate with the logger devices via a radio-link.
Examples of Patroller models are “Patroller 4” and “USB Radio Transceiver”.
These act as an interface, relaying messages between the logger devices and
either a laptop PC or mobile phone.
•
The Laptop PC or mobile phone (with HWM software installed).
This device will provide a Graphical User Interface to the user.
The chosen platform will have a HWM
application (an “app”) installed
, used both
to set-up the devices for use and also to read measurement data from them.
•
HWM application software.
Personal Computers require the
“
PermaNetPlus
” software, and
Mobile phones require the
“WebCorr”
software
The software packages have different graphical user-interfaces and also differing
capabilities.
The PC version keeps a local database of logger details, locations, and
measurement results.
The mobile phone version is integrated with HWM’s cloud
-based
database of logger information.
(Refer to each application manual for a description of its capabilities and how to
use the software).
