5 / 56 ZONESCAN net
Version 1.4
1 Introduction
Gutermann has developed the ZONESCAN net system for professional
leak detection in water networks.
This unmanned, acoustic leak monitoring system with noise-level
measurement and correlation guarantees that leak detection specialists are
deployed only at the actual leak locations.
1.1 Purpose and field of use of the software
Continuous leak monitoring of the entire water network
Distributed over the entire water network, ZONESCAN loggers continuously
monitor and analyze the noise characteristics and can thereby detect the
presence and location of leaks.
Extensive leak database allows for a permanent reduction in water
loss
Each data logger stores the leak analysis results from the last 30 days,
including the detailed noise level distributions from the last 10 days. This
measurement data is automatically stored in the powerful ZONESCAN net
database. This is used to produce detailed logs for the maintenance
personnel and, ultimately, a systematic analysis of historical data for
optimizing future water network planning.
Integration of GPS and GIS in the ZONESCAN net system
The ZONESCAN net system offers the possibility to integrate GPS and
GIS for automatically importing noise level, correlation data and the latest
network information.
1.2 Software functionality
General description
The ZONESCAN net logger is mounted directly on the water network,
where it stores the noises generated along the pipe network and the
ambient temperature. The statistical analysis of the stored values indicates
whether or not a leak is present. A number of strategically mounted
ZONESCAN net loggers allow all segments with water losses to be
identified.
The data measured by the logger is collected by the repeaters, which are
mounted above ground. The repeaters then transmit the data via radio
signal to the ALPHAs. The collected data is then transmitted by means of
GPRS via the ALPHA to your ZONESCAN net program for further
processing.
The software automatically evaluates the collected data daily. The more
exact the pipe data entered by the user, the better the results. The results
calculated in ZONESCAN net are numerically and graphically presented in
