Introduction

Permalog® Plus is the very latest in a highly successful line of permanent and semi-

permanent leak noise loggers. This logger can be used as both a traditional leak noise

logger, and as a "drive by" logger.

Permalog® Plus leak noise loggers are deployed throughout the water distribution net-work

to provide continuous surveying of leakage. Each Permalog® Plus unit adapts itself

automatically to its environment. If no leak is present a signal is transmitted to indicate

normal background conditions, however, as soon as a possible leak is detected, the

Permalog® Plus unit enters an alarm state and transmits a signal to indicate a leak

condition. The logger also incorporates an LED to display the leak status visually.

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. Leak status information from

the loggers is displayed on the PDA screen of the Patroller module and stored in the

memory.

With no cables or hard installation, Permalog® Plus is simply fitted to a metal fixture within

the chamber (usually a hydrant or valve) and left alone. Logging times, Patrol times and

Transmission times are fully customisable ensuring the operator gets the most benefit from

the system and can configure it to their advantage. With integrated Bluetooth technology, the

Permalog® Plus logger offers easy management through the PDA and Patroller Interface

Unit. Permalog® Plus can be fully configured without having to be removed from the

chamber.
