1 Zonescan Loggers Process Flow Chart

Retrieve deployed loggers and

down load data

START

To program the logger,

synchronise PC and all

required loggers using the

COMM LINK via RS232

connection or Blue Tooth

Analyse the leak noise results

Run correlations for each logger

Do results indicate a leak?

Red = probable leak

Amber = possible leak

Green = No leak

Pinpoint with

AQUASCOPE 3

More logging required?

YES

END

Yes

Any loggers which are missed

during synchronization, may be

individually synchronised by

using the ‘Logger State’ facility

(s h o w n a s a n ‘ e y e ’ i c on ) .

Once in the ‘Logger State’

window for the desired logger,

simply select ‘Synchronize’ to

commence synchronization.

8 The Noise Logging Principal

An understanding on how the Zonescan Loggers build the Histogram will help when interpreting the

results. The following section explains how the sampling process works. The tables depict when the

logger takes a noise sample and what the sample is caused by, e.g a passing car or leak. Traffic &

Consumption noise should be ignored. A large number of samples at the quietest level, indicate a

consistant sound that could be a leak which never stops. The Leak is the closest to the loudest,

quietest noise.
