Patroller User’s Guide
Scope
This manual covers the use of the Permalog
®
Patroller in conjunction with
Permalog
®
1 and Permalog
®
2 leak noise loggers.
Introduction
Permalog
®
leak noise loggers are deployed throughout the water distribution
system to provide continuous surveying of leakage. Each Permalog
®
unit
adapts itself automatically to its environment. If no leak is present a signal is
transmitted to indicate normal background conditions (NO LEAK). However,
as soon as a possible leak is detected, the Permalog
®
unit enters an alarm
state and transmits a signal to indicate a LEAK condition.
Patroller used to survey an area
Following a rise in unaccounted-for water,
or at standard intervals, a leakage patrol is
carried out in the area using the Permalog
®
Patroller module. This module receives,
analyses and “homes in” on signals to
identify the location of units in LEAK mode
and thereby the approximate position of
the leaks. Information from the loggers is displayed on the LCD screen and
held in memory. Data from loggers in LEAK mode can be downloaded to a
PC or printed out directly. The Permalog
®
Patroller may optionally be
integrated with GPS or GIS data to enhance the LEAK list with geographical
or system specific information.
Safety warning
The Permalog
®
noise logger contains a high strength magnet and should not
be carried by anyone with a heart pacemaker. This magnet can permanently
corrupt magnetic storage media such as floppy discs, hard discs, tapes etc. It
can also damage TV and PC monitor screens and some watches. See
“Conditions of use”.
Caution.
The Patroller contains a lithium backup battery. There is a danger of
explosion if this battery is incorrectly replaced. It must only be replaced with
the same or equivalent type recommended by the manufacturer. Used
batteries must be disposed of according to the manufacturers instructions.
Warning
When charging from a 12v vehicle supply, if the engine is switched off, the
unit must be disconnected before restarting the vehicle; otherwise permanent
damage to the charge circuits may result. Once the engine is running, it safe
to re-connect the Patroller.
