1 Quick guide

The Correlux P200 uses highly developed measuring techniques and signal processing. Nevertheless, the P200 has been designed to be simple to operate and to show measurement results in an informative manner. To make the most of the full potential of the equipment, however, we recommend that you read these Operating Instructions carefully. The main steps for performing a correlation are explained in the Quick Guide. A detailed explanation follows thereafter.

1.1 Quick guide for TR A / TR B amplifier-transmitters

Function Operation

1. Put transmitter A (orange) at location 1 and fix the sensor to the valve rod or hydrant.

2. Switch transmitter A on.

Align the aerial vertically and close the lid.

3. Put transmitter B (yellow) at location 2 and fix the sensor to the valve rod or hydrant.

4. Switch transmitter B on. Align

the aerial vertically and close the lid.

Fig 1: Setting up the correlator

1.2 Quick guide for Correlux P200 correlator

• Connect a rod aerial or a roof aerial to the aerial socket of the EBox

• Connect the USB EBox to an unused USB position on your computer

• Turn on your computer and click the following icon once the system has started:


7

If necessary, select language in the Start screen, otherwise the program automatically advances.

Start measuring with “Start correlation”. After approx. 3 seconds the first result of the correlation is displayed. When the result shows a clear correlation curve (sometimes it can take a few more seconds before the display becomes clearer), finish the correlation by clicking the Stop symbol.

Now click the “Pipe table” symbol or the “Pipe table” tab

to go to the page where the different pipe sections can be entered. Select the number of pipe sections, pipe data and the respective lengths here and then return to the correlation page (click tab or symbol). You can now see the pipe sections entered underneath the correlation curve, shown diagramatically and assigned directly to the location of the leak found.

2.3 Operating instructions for TR A / TR B

• Positioning the transmitters

Put transmitter A (orange) at location 1 and fix the sensor to the valve rod or hydrant. Put transmitter B (yellow) at location 2 and fix the sensor to the valve rod or hydrant. (Fig 1: Setting up the correlator) The transmitters must always be set up with the aerial pointing upwards.

• Transmitter on Use this button to turn the transmitter on. After switching on, a message first appears about the software version and the remaining battery capacity. This message will disappear after about 3 seconds and the transmitter is then ready to use. After every button push, the background illumination for the display lights up for about 1 minute and then turns itself off automatically. The transmitter automatically turns itself completely off after operating for 2 hours.

• Listening to the leak noise / displaying the level

You can listen to the leak noise via the headphone socket on both transmitters A and B. This means that an assessment can be made before doing the correlation and the user can decide whether the sound picked up is due to water leaking or is due to some other source (a pump, etc.). If necessary, the headphone volume can be adjusted using the arrow

buttons . The noise level is shown on the display both as a bar and as a numerical value. This means that you can easily compare levels at different measurement locations.


11

In “Auto” mode neither the level of the radio signal transmitted nor the sensitivity of the level display are affected by adjusting the volume with the arrow buttons.

3 Correlux P200 software

3.1 “Correlator” display, main screen

The individual elements of the screen are explained as follows. The number in front of the heading is the reference to this picture.

3.1.1 1: Channel A and B time signal display If the time signal is flat and more like a line, a correlation cannot be performed. Possible sources of faults: signal interruptions, a bad contact between sensor and valve, etc.


13

3.1.2 2: Signal spectrum or coherence display Filters are also shown in this window. These can be set simply by clicking and dragging with the mouse in the window.

3.1.3 3: Channel A and B level display This display does not show the radio signal but the strength and quality of the incoming noise signal. If the signals are weak only a limited correlation is possible.

3.1.4 4: Correlation function display The delay time of the cursor position is shown inside the window next to the cursor (symbolised by a red line). Left-clicking with the mouse resets the cursor (automatically reset to the maximum correlation by the software again). Right-click and drag with the mouse in this window to hide certain ranges from the correlation. This function is called “peak suppression”.

3.1.5 5: Diagramatical representation of pipe This diagram does not just show the pipe but also a direct reference to the position of the cursor and hence the leak.

3.1.6 6: Displaying transmitters A and B The distance to the cursor/leak position is shown next to the diagramatical representation of the transmitters.

3.1.7 7: Current pipe data By clicking the table you can automatically go to the input mask to adapt the current pipe data.

3.1.8 8: “Start correlation” button

You can start a correlation with this function. If no pipe data has been entered, start a so-called “overview measurement”, as already


14

described in the Quick Guide. This has the advantage that you can quickly and efficiently check whether there is any noise for a correlation in the chosen pipe section

3.1.9 9: “Start 3D/2D correlation” button

With this function you can show the time constancy of a noise, just as with a data logger. In this way, you can identify sounds that are not constant and are therefore also presumably not a leak. You can choose either a 2-dimensional or a 3-dimensional representation. The change can be made in the “Configuration” menu.

3.1.10 10: Finishing the correlation

Most of the functions are deactivated while a correlation is running. These functions are only available again once the correlation is finished.

3.1.11 11: Changing to the “Pipe table” display


15

By clicking the pipe data (7) underneath the correlation window or choosing the appropriate tab, you can also go to the pipe tables (see also Chapter 3.2).

3.1.12 12: “Reset display”

This deletes all current correlation and pipe data and a new measurement process can be started.

3.1.13 13: “Playback”

If the sound data was also saved during a previous correlation this can be replayed with this button after loading. A correlation is started at the same time and the result displayed in the correlation window.

3.1.14 14: “Automatic frequency analysis”

This performs an automatic frequency analysis and analyses at which filter setting the best correlation takes place. Ten different results are then shown.


16

The best result is shown in red. If you click this window, the correlation is shown in “Normal” mode with the corresponding filter settings. This function helps you to optimise the filter settings and to improve the correlation result. You should, however, analyse the result very carefully to see whether it matches the actual situation.

3.1.15 15: “Measurement statistics”

First the curve shape for the correlation performed is analysed and is allocated a quality factor between 0 and 100. The higher the value, the clearer the correlation. For low values, the button for frequency analysis (14) is shown in the statistics window because an improvement might be possible by altering the filter settings. Result statistics are also displayed. With a measurement process that lasts longer, other louder noises (for example, water being briefly extracted) can affect the correlation and this will result in the cursor (and thereby the distance to the leak) not staying constantly in one position. These values appear in the statistics with low percentage values. This way, the function helps you to better identify the position of the leak.


17

3.1.16 16: Measuring “sound speed”

Measuring the “sound speed” is essential to generate an exact correlation result, especially for unknown pipe materials and pipe characteristics (e.g. old pipes). To measure the sound speed of the pipe, an artificial leak must be created and the distance from this leak to the transmitters must be known. A slightly opened hydrant, for example, is an artificial leak. The leak can be both within or outside the transmitters. It is recommended, however, that the leak is produced outside the transmitters. Place both sensors at suitable measuring points and open the artificial leak. Start a new correlation with the “Start correlation” button (8). Finish the correlation when you have received a suitable result. Now open the “Speed measurement” dialogue by clicking button (16). Enter the corresponding data in the query window.


18

The result is the sound speed of the pipe. Now close the artificial leak and perform the correlation again using the new data to determine the distance to the real leak.

3.1.17 17: “Zoom in”

With this function activated, the correlation curve can be enlarged in the chosen range by clicking and dragging with the mouse in the correlation window. This is particularly useful when two peaks are very close to one another.

3.1.18 18: “Zoom to pipe length”

The correlation window is automatically adjusted so that the length of the pipe fills the whole width of the window. By pressing the button once again, the whole measurement length is displayed again and the pipe is reduced in the middle of the measuring range.

3.1.19 19: “Load correlation”

A saved measurement can be loaded. If sound data was saved this is also loaded at the same time.

3.1.20 20: “Save correlation”

First you will be asked whether you would like to save the actual sounds as well. If you choose “no”, only the correlation curve (diagram) and the report will be saved. Otherwise, the sound data will also be stored in universal WAV format. The saved sound data can be called up at any time again, played back and correlated once again.

3.1.21 21: “Print correlation”

Produces a printout of the correlation curve including a report.


19

If you have also produced a damage sketch, this can be printed out at the same time as well by checking “Sketches”. The sketch will be printed out on a 2nd sheet. The printer selected is always the printer that is defined in Windows as the “default printer”. Please consult Windows Help if you wish to change the selected printer.

3.1.22 22: “Help/Operating instructions”

The Operating Instructions supplied are called up in pdf-file form. You can therefore read about the functions and operation at any time.

3.1.23 23: Filter +/-

When “+” is checked, only the selected range is used for the evaluation. When “-" is checked, this range is excluded from the evaluation.

3.1.24 24: “Wide band”

By clicking this button, the filter is fully opened to the maximum bandwidth.

3.1.25 25: “Coherence / Spectrum A+B”

Used to toggle between coherency representation and display of the individual spectra of the signals sent by the transmitters.


20

3.2 “Pipe table” display

3.2.1 1: Selecting the number of pipe sections

A maximum of ten different sections can be entered. Press the “up” arrow to increase the number of sections. The “down” arrow reduces the number of sections. The total length of all the pipe sections is displayed after the number of pipe sections. The first two sections are shown enlarged to make entry using a touchscreen PC easier.


21

3.2.2 2: Data for the individual sections

The length can either be entered directly via the keyboard or with the two arrow buttons next to the field for the length. The material and diameter are selected from a drop-down list. Click the small triangle directly next to the materials description and select the pipe material from the list. The stored sound speed is displayed underneath. Select the “manual” box to enter the pipe's sound speed by hand. This is necessary if you have carried out sound speed measurements for pipe sections and these do not agree with the stored speeds. In such cases you can improve the correlation result. If this option is set to “manual”, the material and diameter can no longer be selected.


22

3.2.3 3: “Editing the material list”

The user can add other pipe materials and sound speeds to the saved materials list, or alter the list, as many times as they wish. To add materials, click “+” at (1) in the left-hand part of the window. Enter a name for the material in the following dialogue. It is advisable to clearly mark new materials (e.g. with your town as an additional remark) so that you can distinguish them later from the standard materials. To then add the corresponding diameters and sound speeds to the new material, press “+” at (2). Fill in the subsequent dialogues with the corresponding values. You can measure sound speeds using the function of the P-200 that has just been mentioned. Please also read the chapter about this. With the “Standard settings” button, you reset the pipe table back to its original state when the equipment was delivered. CAUTION! All data that you have entered will be deleted. Click

to return to the pipe table or click button (4).


23

3.2.4 4: Returning to the correlation display

3.3 “Multicorrelation” display

This operation mode enables you to compare two or even several measurements on a pipe and replaces a three-point correlation. First carry out a correlation for a pipe section and save the measurement. Now reposition one of the sensors and perform the correlation as normal. To see whether both results agree select the multicorrelation mode. In the upper screen the correlation from the main screen is shown as standard. If required, button (1)

will, however, also enable you to load a saved correlation.


24

The comparative measurement for lower screen (4) is loaded using the corresponding (1). Before this, (2) must still be used to select the sensor that had the same position during both measurements. You can therefore use your first measurement as a reference measurement and compare this with a large number of other correlations in the same range.

3.4 “Report” display

This screen allows you to create a measurement report with a sketch. This report is saved and also printed out together with the correlation.

3.4.1 1: Load background picture

A pipe network map, for example, can be loaded as a background picture. The Correlux P-200 supports, when loading, JPG, BMP, GIF and PNG image formats. If you wish to integrate pictures from your GIS system you must first export a picture in one of the formats mentioned.


25

3.4.2 2: Satellite map

Alternatively, you can also create a picture yourself using satellite-based map material. Click the button. The “MapView” application starts. With this application, screenshots of GoogleMaps can be made and imported (this function is only available when an Internet connection exists). If a GPS mouse is connected, the exact position of the measurement can also be saved as GPS coordinates and the corresponding map loaded in the office later. Please note: The use of map material on the Internet is subject to special conditions of use laid down by the respective providers of the map material. With such use, you accept the terms of the providers of the material. Please consult these terms and conditions beforehand.

3.4.3 3: Undoing the last drawing step

3.4.4 4: Deleting a drawing

3.4.5 5: Creating a new page

3.4.6 6: Selecting the line colour

3.4.7 7: Selecting the fill colour

3.4.13 Loading correlation 13: “Loading correlation”: A saved measurement can be loaded. If sound data has been saved this is also loaded and can be played back afterwards.

3.4.14 Saving correlation 14: “Saving correlation”: Correlation and report are saved. Sound data can also be saved as a WAV file.


27

3.4.15 Printing correlation Press button (15) to produce a printout of the correlation including report. Printing is performed by the default printer.

3.4.16 Help/Operating instructions 16: “Operating instructions”: The operating instructions supplied are called up in pdf-file form.


28

3.5 “Configuration” display

In the “Configuration” display, various basic settings can be made.

3.5.1 1: Skins To enable the interface to be adapted to the particular taste of the user, various user interface designs are provided that can be selected here. You can also create your own by copying existing images into a folder and adapting the icons using a graphics program to suit your personal preferences. This should, however, only be carried out by experienced users. Support for picture creation is not available.

3.5.2 2: “2D/3D” Here you can set the choice of display for the 2D/3D correlation (see “Correlator” display button (9)). The display that you choose will depend on your personal ideas.

3.5.3 Changing the measurement unit to Metric or Imperial Select your desired measurement unit by selecting the relevant option.


29
