period of warranty, SebaKMT agree to repair faulty parts or replace them with new parts
or parts as new (with the same usability and life as new parts) according to their choice.
This warranty does not cover wear parts, lamps, fuses, batteries and accumulators.
SebaKMT reject all further claims under warranty, in particular those from consequential
damage. Each component and product replaced in accordance with this warranty
becomes the property of SebaKMT.
All warranty claims versus SebaKMT are hereby limited to a period of 12 months from
the date of delivery. Each component supplied by SebaKMT within the context of
warranty will also be covered by this warranty for the remaining period of time but for 90
days at least.
Each measure to remedy a claim under warranty shall exclusively be carried out by
SebaKMT or an authorized service station.

3.1 Function
The Correlux C-3 is a digital Correlator 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 Correlator by two
sensors (piezo microphone, hydrophone) which are attached to the pipe (e.g. valve,
hydrants).
The Correlux C-3 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-3 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.
27
Technical description
3.2 Features of the set
The Correlux C-3 set mainly comprises the following components:
•
Correlator
•
2 Power transmitters with microphone (Transmitter A / Transmitter B)
for recording the leak noise at two measuring points and sending the recorded data
to the Correlator
The set can be extended by the following components:
•
up to 8 multi sensors
for recording the leak noise of up to 8 measuring points at the same time followed
by an "Offline-correlation"
•
hydrophones
for recording the leak noise directly at the water column
•
a ground microphone
for pinpointing the leak after correlation
The Transport case offers space for the Correlator, 2 Power transmitters and
3 Multi sensors. The case is not only for storage and transportation purposes, but also
functions as a charging station for the devices.
Using the CorreluxView analysis software measurement data can be displayed and
processed on the computer. The software can be downloaded from the SebaKMT
Internet page:
www.sebakmt.com >> Information > User area > Software > Leak localization

Technical description
3.3 Communication of the components
The components of the system communicate with each other in the following ways:
Participating devices Communication channel
Correlator ļ Power transmitter Short range radio (digital or analogue)
Correlator ļ Multi sensors Short range radio (digital)
Correlator ļ Computer USB cable
Correlator ļ Ground microphone Connection cable
3.4 Power supply
The Correlator, the Power transmitters and the Multi sensors come with internal
rechargeable Li-Ion batteries.
The storage places of the individual devices in the transport case function as charging
stations. As soon as a device is placed in/on its station in the case, the device is
automatically charged, provided the case is connected to the mains.
The case can be connected via the connection socket and the supplied connection
cable to either a 12 V connector of a vehicle or to the mains
NOTE
When connected to the electrical system of a car, the transport case is
powered by the vehicle's battery, even while the vehicle is not in
operation. This could result in the complete discharge of the vehicle
battery.
When you park the car, disconnect the Correlux transport case from the
vehicle power supply.
NOTE
Use inductive charging units inside for COR PT-3 and COR MS-3 only!
NOTE
Close cover of transport case if it is raining!
You can find more information in the chapters which describe the individual devices.
