3 Technical description
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.
Technical description
28
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

4.2 Identification number (ID)
Each Power transmitter has its own six-digit identification number (short: ID). Using this
ID the device can be managed and clearly identified in the Correlator, computer and
within the SebaKMT-Cloud.
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.
When entering an ID on the Correlator or computer, the preceding zero digits can be
omitted.
4.3 Power supply
The Power transmitters are fitted with internal rechargeable Li-Ion batteries This can
power the device for approximately 12 hours.
In the Start menu of the Correlator two battery icons indicate the current battery status
of the Power transmitters.
On the Power transmitters, the current battery status is indicated by the LED bar
when it is green. If only one of five LEDs is lit, the device should be charged. Otherwise,
it switches itself off automatically.
Red light represents the recorded noise during the measurement and not the battery
status.
The Power transmitters are charged wirelessly in the transport case. The case must be
connected to a power supply. As soon as the Power transmitters are situated at their
storage places in the case, they are recharged inductively.
Charging takes approximately 12 hours. The I/O LED flashes when loading. The
LED bar indicates the progress of charging The I/O LED turns back to permanent
light as soon as the battery is full.
CAUTION
No objects must be put into empty charging stations.
Risk of fire!
The charging stations are for transport and charging of the devices only.
NOTE
Any repairs must be carried out by SebaKMT or an authorized service
partner.
Otherwise, the devices' resistance against water and dirt cannot be
guaranteed.
Do not open the device yourself. If you have problems with the battery,
please contact your SebaKMT service partner.

4.4 Commissioning
To turn on, briefly press the I/O pushbutton . The I/O LED is lit green when the
device is turned on. To turn the device off, press the button until the LED goes out.
The microphone's storage place is fitted with a magnetic switch. As a result, the
Power transmitter "knows" whether the microphone is currently in use or not.
As long as the microphone rests in its storage place, the Power transmitter remains in
"Stand-by" mode. The internal analogue radio module stays off as no measuring data
needs to be transferred to the Correlator. 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 radio module is activated. 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.
4.5 Installation
The sensors should be installed directly on the pipe but, however, you can also attach
them to valve rods or hydrants, for example, or any other position along the pipeline that
is easily accessible.
There must be the best possible contact between the sensor foot or the mounted
adapter (see below) and the pipe. If need be, clean the contact point thoroughly
(preferably with a wire brush).
In some situations it might be helpful to use one of the supplied magnetic angle
adapters.

identified.
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.
When entering an ID on the Correlator or computer, the preceding zero zero digits can
be omitted (see page 45).
The Multi sensors
38
5.3 Power supply
The Multi sensors are fitted with internal rechargeable Li-Ion batteries This can power
the device for at least 16 hours.
In the Start menu of the Correlator up to eight battery icons can be seen. They indicate
the current battery status of the registered Multi sensors in reach. To know the exact
battery state of a Multi sensor, read the unit's configurations menu (see page 111). In
the line battery status the battery level of the sensor is shown as a percentage.
When the battery level of a Multi sensor falls below a certain threshold, the indicator
light of the device will flash red. The device must be charged. Otherwise, it switches
itself off automatically.
To charge the Power transmitters place them in the transport case. The case must be
connected to a power supply. As soon as the sensors are situated at their storage
places in the case, they are recharged inductively.
Charging takes approximately 6 hours. The units' indicator lights are rapidly flashing
during the charging process. The indicator lights turn to permanent green light as soon
as the battery is full.
CAUTION
No objects must be put into empty charging stations.
Risk of fire!
The charging stations are for transport and charging of the devices only.
NOTE
Any repairs must be carried out by an authorized service partner.
Otherwise, the devices' resistance against water and dirt cannot be
guaranteed.
Do not open the Multi sensors yourself. If you have problems with the
battery, please contact your SebaKMT service partner.
5.4 Switching ON/OFF
The Multi sensors have an internal magnetic switch.
To turn a Multi sensor on, briefly hold a magnet (e.g. the foot of another Multi sensor) in
front of the sensor's I/O area . The device turns on. The indicator light flashes
3 times.
To turn the device off, hold a magnet in front of the I/O area for approximately
2 seconds. The indicator light will flash 2 times before it goes out.

5.5 Installation
The Multi sensors should be installed directly on the pipe However, you can also attach
them to valve rods or hydrants, for example, or any other position along the pipeline that
is easily accessible. Due to their powerful magnet, the sensors can also be attached
horizontally.
There must be the best possible contact between the sensor foot or the mounted
adapter (see below) and the pipe. If need be, clean the contact point thoroughly
(preferably with a wire brush).
5.6 Angle adapter
In some situations, the Multi sensor cannot be attached directly to the desired
measurement point due to its size, e.g. in very narrow shafts or similar. In such cases, it
can be helpful to use one of the supplied angle adapters.
Thanks to its magnetic foot, the sensor is simply placed on the
adapter. Then, the magnetic adapter can be attached to the
pipe or fitting etc.
NOTE
The sensor's type plate and I/O area must face
away from the angle adapter - as can be seen on
the picture.
Otherwise, the magnet of the angle adapter would
turn off the Multi sensor unintentionally.
You can screw the angle adapter firmly to the sensor.
This can be useful as the holding strength between the angle adapter and the pipe in
general is higher than the holding strength between the angle adapter and the sensor.
When collecting the sensors, it may happen that you pull the sensor from the angle
without intention. The adapter then remains on the pipe and it could be difficult to
remove it.
Unscrew the magnetic foot from the sensor. Take one of the
supplied screws from the Correlux C-3 set to screw the angle
adapter on the sensor.
Make sure that the sensor's type plate does face away from the
angle adapter.

the screen. The device must be charged. 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 its 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 before it switches off.
Charging takes approximately 9 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 inside
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:
•
Use only the charging station in the transport case. Do not use other
chargers.
•
The ambient temperature should be between 10°C and 35°C

8.1 Measurement with 2 Power transmitters
The following requirements must be met or preparations must be made:
•
The batteries of the Power transmitters and the Correlator must be charged.
•
All radio antennas have to be properly connected to the Power transmitters and the
Correlator.
•
The microphones/hydrophones have to be properly connected to the Transmitters.
•
The radio of each Power transmitter should be tested. For this, take the
transmitter’s microphone from the storage place. The Radio LED must now be
lit. If not, put the microphone back to the storage place, switch the transmitter off
and on again and repeat the test.
Deploy the Power transmitters at the required measuring points and start the correlation.
Proceed as follows:
Step Description
1 Take the Power transmitter "A" (orange) and go to the first measuring point.
Attach the microphone to the pipe (or, alternatively, install the hydrophone).
Switch the Power transmitter on.
2 Take the Power transmitter "B" (yellow) and go to the first measuring point.

If the radio symbol shows a weak signal, a continuous correlation will
be hardly or not possible.
The following actions may help:
•
Move closer to the Power transmitter in question.
•
Place the transmitter higher
(e.g. on a wall or on a traffic cone or similar).
•
If necessary, place the transmitter at an other measuring point.
•
If possible, there should be a direct line of sight connection between
Correlator and transmitter.
If still no connection can be made, conduct an Offline measurement instead
of the Online measurement.
Is the correlation result reliable?
The curve shows one clear peak;
the lag value is green or yellow
and does not fluctuate
The curve shows no clear peak;
the lag value is red and fluctuating
Meaning: The result is reasonable.
How to proceed: Continue the
measurement and start a detailed
analysis.
How to proceed: If you still suppose a leak to be
here, the following can help:
•
Access the system settings menu, adjust the
„Averaging“ to “unlimited” and restart the
correlation.
•
Conduct an Offline measurement (at night)
instead of the Online measurement.

If the answer is YES, the leak is located precisely at the measuring point or outside the
correlated pipe section.
Cancel the measurement. Take the relevant transmitter and look for a new installation
point in order to enlarge the measuring length. Then start a new correlation.
Does each value show the half of the measuring length
If the answer is NO, the values seem plausible.
Continue the measurement and start a detailed analysis.
If the answer is YES, the leak is located precisely half way between the measuring
points or a measuring error has occurred (so called ‘center point correlation’).
Cancel the measurement. Take one of the transmitters and look for a new installation
point in order to enlarge the measuring length. Then start a new correlation.

A group of 2 to 8 sensors is programmed for measurement and then deployed at the
measuring points. Multi sensors and/or Power transmitters can be used. The
measurement is carried out by all sensors simultaneously. During the measurement,
there is no contact between the sensors or between the sensors and the Correlator.
After the measurement, the sensors are collected and the recorded data is read, then
correlations can be carried out and displayed on the Correlator.
The following requirements must be met or preparations must be made:
•
A digital or printed pipe network plan of the relevant measuring area with all pipe
parameters is needed.
•
The batteries of the devices involved must be charged.
•
All sensors involved must be registered in the Correlator's Multisensor pool (also
called "Offline pool" (see page 55))
•
If Power transmitters will be used: The microphones must be properly connected.
•
All sensors must be received by the Correlator. (This is the case, when each battery
icon in the Correlator's Start menu shows the battery level of the relevant sensor. If
a question mark is shown, the corresponding sensor cannot be reached.)
Configure the sensors for the measurement:

12 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.
12.1 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:
•
Two Power transmitters (PT-A and PT-B) at two measuring points.
•
The distance between the measuring points must be known.
•
The noise must be clearly measurable for both sensors.
•
The source of noise may be inside or outside the measuring section.
•
The source of noise should not be half way between the measuring points.
•
If the source of noise is inside the measuring section, the distance from the first
measuring point to the sound source must be known.

Proceed as follows:
Step Description
1 Position the Power Transmitters at both measuring points, attach the sensors
(Microphone / Hydrophone) to the pipe and switch the Power Transmitter on.
There must be radio contact between the Power transmitters and the Correlator.
(The two battery symbols in the Correlator’s Start screen can be seen. These
must show the battery level of the Power Transmitter. Question marks are shown
if the Power transmitters are not available.)
2 Make sure the required sound source does exist.

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

12.2 Velocity measurement in Offline measurement mode
12.2.1 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 analyzed 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 determine sound velocity or the leak
position:
•
A measurement (night or instantaneous measurement) with at least 3 sensors has
been performed.
•
The measured data has been read and saved with the Correlator.
•
Between 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).
•
The lengths of the pipe sections between the measuring points must be known.
•
The 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).

12.2.3 Notes and examples
Take care to follow this scheme at the bottom of the display area when selecting the
three sensors (see step 4). Otherwise the result of the calculation may be wrong.
There must be one sensor "in front" and two sensors "behind" the source of noise. The
sensors' numbers and their order on the pipe are of no importance in this process.
The source of noise is located between the sensors 1 and 2.
Entry on the Correlator: first, sensor 1 (in front of the sound source), then sensors 2 and
3 (behind the sound source).
The source of noise is located between the sensors 2 and 3.
Possible entry: first, sensor 2, then sensors 3 and 4.
Possible entry: first, sensor 3, then sensors 2 and 1.

16 Pinpointing
16.1 Introduction
After a leakage has been identified and pre-located by a correlation, the Correlator can
be used to pinpoint the leak position.
In the area of the pre-located leak position, individual measurements are performed at a
number of measuring points along the probable pipe run. The noise levels recorded are
displayed on the Correlator. The closer a measuring point is to the leak, the louder the
recorded sound.
To determine the leak position accurately, a number of pinpointing runs are carried out
in succession. With each new run, a smaller distance between the measuring points is
chosen. This way, you will gradually approach the exact leak location.
The Correlux C-3 system allows two variants of how to conduct a pinpoint location:
2 options
Pinpoint location using the
ground microphone
Pinpoint location using
Multi sensors
The optional ground microphone is
connected to the Correlator.
Individual measurements are performed in
sequence along the pipe at a number of
measuring points.
The measured values are displayed "live"
on the screen of the Correlator.
You can listen to the recorded sound "live"
via headphones.
Up to 8 Multi sensors are placed at the
desired measurement points on the
ground. Actually, they are used as ground
microphones.
A measurement is performed by the
sensors.
The measured values are displayed "live"
on the screen of the Correlator.
16.2 Pinpointing using the ground microphone
The following preparation work is necessary if you want to perform a pinpoint location
using the optional ground microphone:
•
Connect the ground microphone PAM W2 to the Correlator using the supplied
VK 100 connection cable. Observe the markings on the plug and socket. You must
feel the plug engage.
The Correlator's microphone socket has this icon:
•
If you want to listen to the leak noise, connect the supplied headphones to the
Correlator. Use the 12 V DC / socket.
•
Have any object/s ready which can be used during the pinpoint location to mark the
position where the loudest sound will be measured.

106
Up to 10 measurement results can be displayed side by side. If more than 10
measurements are performed, always the oldest result (displayed on the very left) is
dropped out of the row in favor of the new result.
Ideally, the minimum value increases with every measurement as long as you move
toward the leak. The minimum value decreases again after you have passed the leak
position.
The drop symbol identifies the measurement with the highest minimum value.
This means that the leak noise at this measuring point is the loudest.
Example:
After the first pinpointing run is performed, you know the approximate location of the
leak. Furthermore you have an idea of the frequency spectrum and you are able to
assess whether the microphone gain needs to be changed or not.
Adjust the microphone gain
If the height of the level bars on the screen does only change very little from
measurement to measurement, you should increase the microphone gain (moving slide
control in the top left of the screen to the right).
If the height of the level bars does change much too much, you should reduce the
microphone gain (moving slide control in the top left of the screen to the left).
Adjust the Frequency filter
If the frequency values of the individual measurements share a common range, you can
change the frequency filter from the Broad band setting to this frequency range (see
step 6).
Perform further pinpointing runs
After the filter settings and microphone gain have been adjusted where necessary,
perform one more pinpointing run along the pipe in the area of the pre-located leak. This
time, choose a shorter distance between the measuring points.
Perform more pinpointing runs with increasingly smaller distances between the
measuring points.
The leak is considered reliably localized if multiple pinpointing runs show the leak at the
same position.

16.3 Pinpointing using Multi sensors
In the area of the pre-located leak position, up to 8 sensors are placed on the ground
along the pipe. The devices record ground noise and send data to the Correlator.
Multi sensors as well as Power transmitters can be used.
The following requirements must be met:
•
All sensors to be used must be registered in the Correlator's Multi sensor pool (also
called "Offline pool" (see page 55)). This applies to both Multi sensors and
Power transmitters.
•
All measuring points must be within the Correlator's radio range.
Attach the supplied Trivet adaptors to the sensors in order to ensure safe standing and
best possible contact to the ground. Thanks to their magnetic foot, the sensors simply
have to be put on the trivets.
Switch the sensors on and put them on the ground, evenly spaced, along the pipe.

As long as the pinpoint location is in progress, in regular periods the currently measured
value of each sensor is retrieved by the Correlator and displayed. In addition, the lowest
measured value (Minimum value) of the current measurement is displayed for each
sensor.
The bar's height represents the noise level.
