Function
The Correlux C-300-RI is a digital correlation system to locate leaks in drinking water
pipes.
Pressurized water at the leak location creates a noise which travels out in all directions
of the pipe. This noise is recorded, amplified and sent wirelessly to the correlation
system by two sensors (piezo microphone, hydrophone) which are attached to the pipe
(e.g. valve, hydrants).
The PC software compares both signals (correlation) and calculates the exact distance
to the leakage on the basis of the delay time of the signals, the sensor spacing and the
sound velocity in the pipe.
The
Correlux C-300-RI
is
suitable
for
both
immediate
measurement
("Online measurement") as well as time-delayed measurement ("Offline measurement").
Online measurement
In a so-called Online measurement, the noise recording and the correlation of the data
take place at the same time.
Step Description
1
Installing the Power transmitters "A" and "B" at two measuring points.
2
Noise recording, at the same time data transfer and live data correlation on the
Correlator.
Offline measurement
In a so-called Offline measurement, the correlation of the measured data takes place
only after the noise recording has been terminated.
Step Description
1
Programming the sensors (Multi sensors and Power transmitters)
2
Installing the Power transmitters and/or Multi sensors at up to 8 measuring points.
3
Noise recording, immediately or at a preset time (e.g. at night).
4
Collecting the sensors.
5
Reading and analyzing the measured data using the Correlator.
Pinpointing
To determine the exact location of the leak after the correlation, a pinpoint search can
be performed using the Multi sensors or the ground microphone connected to the
Correlator.
