Technical description253 Technical description3.1 FunctionThe 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 measurementIn a so-called Online measurement, the noise recording and the correlation of the data take place at the same time.Step Description1Installing 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 measurementIn 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.PinpointingTo 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.

The Correlator334.2 Power supplyThe 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 onthe 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 atemperature 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.NOTEIn order to prevent damage, observe the following precautions when charging:xUse only the charging station in the transport case. Do not use otherchargers.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.Charging

The Correlator354.4 Basics of operation4.4.1 Input methodsEntries can be made directly on the screen or via the rotary encoder.2 ways of entering dataTouch display Rotary encoderThe 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 selectedbutton (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): 0888000225Identification number (ID): 000225Entry on correlator / PC: 225You 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 Correlator36For entering a device ID the following screen view, or a similar one, opens:DEL … Deletes the last characterENTER … Confirms and completes the inputAccept … Accepts and enters the automatically detected IDDecline … Does not accept the automatically detected IDFinish … Completes the automatic detectionFor 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.

The Power transmitters475.3 Power supplyThe 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. NOTEIn 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 thebattery, please contact your SebaKMT service partner.5.4 CommissioningTo 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.

Sound velocity measurement6710 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 thePower 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.RequirementsSource of noisedistancedistanceMeasuring point 2Measuring point 1

The sound velocity in the pipe is calculated and displayed below the correlation curve.The result is considered reliable if the following criteria are met:xThe radio signal from both transmitters is good or excellent.xThe lag value (top left of the diagram) is green and seems plausible.xThe displayed sound velocity seems stable and plausibleIf no reliable result is shown, you can use the Cancel button to terminate the measurement and leave the menu. 11 Tap the Accept and edit pipe button.Result: The Pipe data menu opens. There, for the Material and Diameter input fields, the “Manual” option is automatically selected. The recently calculated sound velocity is accepted and shown in the corresponding field.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.
Sound velocity measurement7010.2 Velocity measurement in Offline measurement mode 10.2.1 IntroductionThe 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 optionsDetermining 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).RequirementsSource of noisedistancePosition 2Position 1 Position 3distance

GPS position data7311 GPS position data11.1 IntroductionYou 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 Offlinemeasurement. 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 coordinatesTo determine the GPS position for a sensor, you must take the Correlator and proceed as close as possible to the installed device.Proceed as follows:Step Description1In the main menu, tap the button .2In the displayed menu, tap the Store GPS position button.Result: The following menu is opened. The up to 8 fields represent the sensors registered to the Correlator's "Multisensor pool". (continued on next page)RequirementsSensor IDSensor no.GPS position
