3.1 Function
The Correlux C-3 correlator locates 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-shifted measurement ("Offline measurement" or "Night 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
1Installing the Power transmitters "A" and "B" at two measuring points.
2Noise 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
1Programming the sensors (Multi sensors and Power transmitters) using the
Correlator.
2Installing the sensors at up to 8 measuring points.
3Noise recording, immediately or at a preset time (e.g. at night).
4Collecting the sensors.
5Reading 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.
Technical description
26
3.2 Features of the set
The Correlux C-3 set mainly comprises the following components:
xCorrelator
x2 Power transmitters with microphone
for recording the leak noise at two measuring points and sending the recorded
data to the correlator for an Online correlation
The set can be extended by the following components:
xup to 8 Multi sensors
for recording the leak noise at up to 8 measuring points simultaneously, followed
by an Offline correlation
xhydrophones
for recording the leak noise directly at the water column
xa 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.
3.3 Communication of the components
The components of the system communicate with each other in the following ways:
Participating devices Communication channel
Correlator Power transmitter Short range radio (digital or analogue)
Correlator Multi sensors Short range radio (digital)
Correlator Computer USB cable
Correlator Ground microphone Connection cable
Technical description
27
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 mains or to a 12 Volt vehicle
power supply.
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.
You can find more information in the chapters which describe the individual devices.

4.2 Power supply
The Correlator is fitted with an internal rechargeable Li-ion battery. This can power the
device for approximately 16 hours. The battery’s present charge level is shown
continuously by the battery symbol bottom right of the screen.
When the battery is low, a warning tone is heard and a warning message appears on
the screen. The device must then be recharged, otherwise, it switches itself off
automatically.
The correlator is charged wirelessly in the C-3 transport case.
As soon as the device is situated at it's storage place in the case, it is recharged via the
two pins , provided the case is connected to mains or a 12 Volt vehicle power
supply. The red indicator light is lit while the device is charging.
The correlator is switched on during the entire charging process and can not be
deactivated. After the end of charging, the device remains switched on for the Auto-OFF
period specified in the system settings.
Charging takes approximately 12 hours.
Heat is generated while charging. The charging station in the case therefore has a
temperature switch. The charger switches off automatically when it gets too warm in the
case. It turns back on as soon as the degree of heat has fallen below a certain level.
NOTE
In order to prevent damage, observe the following precautions when
charging:
xUse only the charging station in the transport case. Do not use other
chargers.
xThe ambient temperature should be between 10°C and 35°C
(50°F and 95°F).
xTo avoid heat accumulation, do not close the lid of the case at high
ambient temperatures during charging.
xIf you experience problems with the battery, please contact your
SebaKMT sales partner. Do not open the device yourself.

4.4 Basics of operation
4.4.1 Input methods
Entries can be made directly on the screen or via the rotary encoder.
2 ways of entering data
Touch display Rotary encoder
The correlator screen is touch-sensitive.
All entries can be made directly on the
screen.
The correlator has a rotary encoder.
All entries can be made using the rotary
encoder.
The buttons or fields displayed can be
called or executed by tapping with your
finger.
Turn the rotary encoder to navigate
through the displayed buttons.
Press the encoder to call the selected
button (ENTER function).
You can always switch between operating via touch screen and operating via rotary
encoder.
4.4.2 Entering identification numbers (IDs)
Various functions require the identification numbers (IDs) of the Power transmitters or
Multi sensors to be specified.
The ID is deduced from the last six digits of the device's serial number (short: SN). You
find the serial number on the nameplate of the device.
Example:
Serial number (SN): 0888000225
Identification number (ID): 000225
Entry on correlator / PC: 225
You can enter device IDs manually or you can use the "Automatic device detection".
Automatic detection means that, when a device is activated its ID is sent to the
Correlator. There, it is detected and displayed.
Introduction
The Correlator
36
For entering a device ID the following screen view, or a similar one, opens:
DEL … Deletes the last character
ENTER … Confirms and completes the input
Accept … Accepts and enters the automatically detected ID
Decline … Does not accept the automatically detected ID
Finish … Completes the automatic detection
For the manual entry of IDs, the number pad displayed is used. Confirm your entry with
the ENTER button.
When inputting an ID, the preceding zero digits can be omitted.
Thus, if the ID is ‘000225’, you need only enter ‘225’.
To the right of the number pad, there are fields and buttons for the automatic sensor
detection. The devices concerned must be close to the correlator.
To register a Power transmitter to the correlator, briefly press the I/O pushbutton of the
device. To register a Multi sensor, briefly move a magnet past the sensor's I/O area, so
that the LED lights up briefly. As a result, the device's ID is sent, detected by the
Correlator and displayed there. Use the provided buttons to accept or decline the ID.
This way, multiple sensor IDs can be registered to the Correlator in quick succession.
4.4.3 Entering text
To input comments or similar, a virtual keyboard appears on the screen. Enter the
required text and confirm with OK.

4.4.4 Sorting devices in lists and tables
In various menus, device IDs or other information are listed in a kind of table.
For example, the following picture shows a list of all Multi sensors registered to a
Correlator (the so called 'sensor pool').
If a black triangle can be seen in the header of a column, you have the chance to
change the sort order (ascending / descending) according to the parameter shown in the
header. Just tap the respective header.
Changing the sort order is only possible via touch screen, not via the rotary encoder.
4.4.5 ESC pushbutton and Back button
You can use the ESC pushbutton to cancel any started function and exit each
menu. This immediately returns you to the start screen.
You can use the Back button in the main menu bar to return to the previous
menu level.

5.3 Power supply
The Power transmitters are fitted with internal rechargeable Li-Ion batteries which can
power the devices for at least 12 hours.
On the device, the current battery status is indicated by the row of LEDs when it is
green. (Red light represents the recorded noise.) If only one of five LEDs is lit, the
device should be charged. Otherwise, it switches itself off automatically.
In the Start menu of the correlator two battery icons indicate the current battery status of
the Power transmitters, provided both devices are switched on and in reach.
To know the exact battery state of a Power transmitter, read the unit's configuration and
see the Battery level line in the respective menu.
The Power transmitters are charged wirelessly in the transport case.
As soon as the devices are situated at their storage places in the case, they are
recharged inductively, provided the case is connected to mains or to a 12 Volt vehicle
power supply.
Charging takes approximately 12 hours. The row of LEDs indicates the charging
progress. The I/O-LED is flashing during the process. It returns to permanent light
as soon as the battery is full.
NOTE
In order to guarantee the devices' water and dirt resistance, any repairs
must be carried out by SebaKMT or an authorised service partner.
Do not open a Power transmitter yourself. If you have problems with the
battery, please contact your SebaKMT service partner.
5.4 Commissioning
To turn a Power transmitter on, briefly press the I/O pushbutton . The I/O LED is lit.
To turn the device off, press the button until the LED goes out.
The Power transmitter's sensor storage place is fitted with a magnetic switch. As a
result, the transmitter "knows" whether the microphone is currently in use or not.
As long as the microphone rests in the storage place, the Power transmitter remains in
"Stand-by" mode. The internal analog radio module stays off as no measuring data
needs to be transferred. This saves battery power.
As soon as the microphone is taken from the storage place, the Power transmitter
switches from "Stand-by" to "Active" mode. The internal radio module is activated and,
from now on, the recorded data are directly sent to the correlator. The row of LEDs
switches from green to red and represents the recorded noise level.

The Multi correlation gives you an overview of the noise situation along the measured
pipeline. In the ideal case, the pipe sections where leaks are most likely can be
identified at a glance.
Rate the displayed correlations.
"Good correlation"
xclear peak
xlag value is green
xlag value is not zero
Probability of a leak is high
"Bad correlation"
xmore than one peak
xlag value is yellow or red
xlag value is zero or nearly zero
No leak or no clear localization possible
If the Multi correlation shows at least one "good correlation" with one clear peak, the
probability of a leak between the respective sensors is high.
Take a closer look at the good correlations. Tap the relevant thumbnail. The
Correlation menu for this sensor pair is opened.
To be able to calculate the distance to the leak the properties of the pipe have to be
specified.
You can call the Pipe data menu directly and enter the parameters for the pipe between
the two sensors.
However, we recommend instead to switch to the "Map" menu now. This menu offers a
good overview of the used sensors and the sections of the pipe. The Map menu can not
only be used to specify the pipe parameters for all pipe sections, but also to carry out
more correlations. You find detailed information about the Map function in a separate
section of this manual.
If there is no complete pipe data available, you have the chance to switch now to the
"Velocity measurement" menu.
This menu is for:
xCalculating the distance between a sensor and the leak, although material and
diameter of the pipe are unknown.
xCalculating the sound velocity in the pipe. The value can then be adopted for
further correlations.
You find detailed information on how to use the Velocity measurement function in a
separate section in this manual.

Sound velocity measurement
67
10 Sound velocity measurement
The Correlux C-3 system can be used to perform a sound velocity measurement in
order to determine the actual speed of sound in a pipe section.
This function is useful when no reliable information on the pipe material is available for a
pipe section or the entire measurement area. The calculated sound speed is then
accepted by the Correlator and used for the correlation.
The calculation of the speed of sound is possible in both the Online measurement as
well as the Offline measurement mode.
10.1 Velocity measurement in Online measurement mode
The Velocity measurement function compares the measuring values of the
Power transmitters while they are recording the noise from one specific source. The
sound velocity in the pipe is calculated using the sound delay.
There must be a source of noise on the pipe, which is clearly measurable for both
sensors. If such a noise source does not exist, it must be created artificially, for
example, by opening a fire hydrant.
The following conditions must be met in order to use the function:
xTwo Power transmitters (PT-A and PT-B) at two measuring points.
xThe distance between the two measuring points must be known.
xThe noise must be clearly measurable for both sensors.
xThe source of noise may be inside or outside the measuring section.
xThe source of noise should not be half way between the measuring points.
xIf the source of noise is inside the measuring section, the distance from the first
measuring point to the sound source must be known.

1Position the Power transmitters at the measuring points, attach the sensors
(microphones/hydrophones) and switch the devices on.
There must be radio contact between the Power transmitters and the Correlator.
(If there is a connection, the two battery symbols in the Correlator’s Start screen
reproduce the Power transmitters’ battery level. Question marks are shown if the
Power transmitters are not available.)

Once the length of the pipe section is changed in this menu, the sound
velocity measurement must be performed again.
Use the Back button to return to the Start menu.
Use the button to start a new correlation between the Power transmitters. The
determined sound velocity will be used for the calculation. This applies until the pipe
parameters are changed in the Pipe data menu, or the entire correlation data are reset
in the Settings menu.

10.2 Velocity measurement in Offline measurement mode
10.2.1 Introduction
The Velocity measurement function compares the measuring values of three sensors
which have recorded a shared noise. As a result, the following applications are possible:
Application options
Determining the sound velocity
in the pipe
(for an unknown pipe material)
Determining the position of a leak
(despite unknown pipe material)
The actual sound velocity in the pipe is
calculated.
This value can then be adopted for the
pipe section being analysed as a pipe
parameter.
The correlation curve will be updated on
this basis.
The distance from a certain measuring
point to the leak position is calculated.
The following conditions must be met in order to use the function:
xA measurement (night or instantaneous measurement) with at least 3 sensors has
been performed.
xThe measured data has been read and saved with the Correlator.
xBetween the three considered sensors exists a clearly perceptible source of noise.
(The louder the noise, the lower are the negative effects of any potential
interference on the result of the sound velocity calculation).
xThe lengths of the pipe sections between the measuring points must be known.
xThe measuring points and sound source must be arranged as shown on the
following picture.
There must be one sensor „in front of“ the sound source (Position 1).
There must be two sensors “behind” the sound source (Positions 2 and 3).

11 GPS position data
11.1 Introduction
You can use the Correlator to determine and store the GPS coordinates of the individual
measuring points.
GPS data facilitate the management and analysis of the measured data in the Offline
measurement. For some analysis capabilities GPS data are even a prerequisite.
The GPS receiver LOG GPS-3 has to be connected to the Correlator.
The GPS module is connected using the USB/GPS socket . Observe the markings
on the plug and socket. You must feel the plug engage. The GPS module is powered via
the USB connection. The device switches on immediately after connection and is ready
for operation. The status LED lights up. The device is detected automatically by the
Correlator. Further settings are not required.
11.2 Determine and save GPS coordinates
