6 Preparing Measurements
Note:
The measurement preparation is described in two se-
parate sections. You always need to perform all
steps from both sections, 1 and 2, to prepare a
measurement completely.
When the system is taken into service for the first time,
it is also required to perform the steps listed under
”Preparation - Part 1”.
6.1 Preparation - Part 1
Switch off your computer, provided that it is switched on.
Place the SePem devices into the slots of the charging adapter.
While doing so, turn the devices slightly until they lock into place.
Note:
Ensure that the SePem devices are correctly locked
in the charging slots. Only then the data transmission
can be performed correctly. During data transmission,
the SePem devices must not be taken from the
charging adapter. If devices with rechargeable
batteries (accumulators) are used, it is required to
charge them before the system is taken into service
(see chapter 9).

7 Intended Purpose and Principle of Operation
The SePem 02 system is modularly structured. It is designed to
be used with different sensors. Therefore, it can be used for a
wide range of applications. (See chapter 14 for information on
exchanging sensors.)
7.1 Noise Sensors
SePem devices with inserted noise sensor can be used for
localizing leaks in water-supply distribution systems (remote
detection).
Electro-acoustic processes for localizing water leaks depend to
a large extent on the intensity of the ambient noise. For this reason,
it is often unavoidable to check the pipeline networks during the
night - i. e. outside the regular working hours. The SePem system
is based on sound level measurements and offers a reasonably
priced and efficient alternative to nightshift work.
7.1.1 Functionality and Measuring Principle
The SePem devices take over the sound recording directly on-
site. All present sound signals are amplified and filtered (50 Hz
filter). The sound level is determined using filtered signals.
Noise sensors allow to measure the following:
Volume level
Complete sound samples
7 Intended Purpose and Principle of Operation
Page 35
33
7.1.1.1 Volume Level
The sound volume levels are measured over a pre-set period of
time. During the measurements, the SePem devices record in
specific chronological intervals the present sound level and further statistical data.
Evaluation
When the sound level is very low during the measurement (mea-
sured value close to 0), there is no leakage in the area which
can currently be detected by the SePem devices.
A continuously high sound level is a reliable indicator for a leak,
since it generates a permanent and uniform noise signal (see
also graphics of the measurement details in chapter 11.1.1.10).
The absolute volume of the leak sound level may vary extremely
since this value depends on the size of the leak and the distance
between device and leak.
Consumption noise caused, for example, by water being drawn
off by a consumer, occurs only during the draw-off. Depending
on the quantity of the flow rate, an sound level is generated during the draw-off period reflecting the consumption.
Interfering noise on the other hand, caused by background
noise, cars, etc., generates sound patterns with increasing and
decreasing intensity.
7.1.1.2 Complete Sound Samples
Sound samples are also recorded over a pre-set period of time.
During the measurement, the SePem devices detect internally
the point of time at which the minimum sound level is present.
Then, the measurement is started for a defined time. During the
measurement, all sounds are recorded.
Evaluation
You can listen to the sound sample at the PC. Usually, leaks can
be clearly distinguished from interfering noise.
7 Intended Purpose and Principle of Operation
Page 36
34
7.1.2 Procedures for Recording Data
Basically, the SePem 02 system provides two different approa-
ches for handling data recording.
On the one hand, the individual data loggers can be regularly
moved, for example after one or two measurement nights. For
this purpose, the SePem software provides a wide range of
functions for planning measurement cycles and conditioning
the data which is read out at the end of a measurement period.
On the other hand, SePem devices can be used stationary -
thanks to the GSM module. This extra feature permits to monitor
crucial spots within the pipeline network continuously. Otherwise
these spots could only be controlled with considerable effort.
7.1.3 Problems during the Application of Noise Sensors
The SePem 02 system cannot make a distinction between cer-
tain types of interfering noise, such as pumps, transformers, etc.,
which are generating a steady and uniform sound signal and the
noise generated by leaks.
To detect interfering noise nevertheless, the SePem software is
provided with several options of how to display and evaluate the
measurement results:
Combination of different display types (e. g. frequency spec-
trum, histogram, representation as a chronological function)
Acoustic control with the help of sound samples
7 Intended Purpose and Principle of Operation

7.2 Installing SePem Devices at the Measurement Location
You can install the SePem devices in defined spaces at the pipe-
line system.
Recommendation for determining proper spacing
Provided that the spacing between the hydrants is 100 m:
metallic pipeline systems: every 2
nd
hydrant
non-metallic pipeline systems: every hydrant
The sound is recorded automatically in user-defined cycles.
Note:
The transmission of the structure-borne sound must
not be dampened by dirt, mud or rust.
If required, clean the coupling positions before
installing the adapter.
The acoustic coupling is realized with the help of various adapters.
The following table is an overview of the adapters and other accessories which can be used for the different types of coupling
positions.

they are, for example, collected after two measurement nights
(typical practice-oriented value. They can then be installed at the
next hydrant or connected to a PC for evaluating the data.
Note:
Max. 50 SePem devices can be read out at the same
time.

8.3.2 Setting Up or Modifying a Measurement Time Scheme
The SePem software functions are based on a measurement time
scheme. The measurement time scheme is used to determine
when the measurements are to be started, how long they should
take and in which cycles they are to be performed (for example,
on five consecutive days with two measurements per night). Measurement time schemes offer the advantage that the measurement times need only to be entered once.
The scheme contains a varying number of entries which are
modifiable.
After installing the software, the measuring-time scheme is still
empty. This means, before placing the SePem devices for the
first time the required data has to be entered or modified.
Proceed as follows if you want to set up or modify the measurement time scheme:
Click on the Meas. times button in the Expose devices window.
The Adjust measurement scheme window is opened.

8.3.5 Transmitting Settings to the SePem Devices and Printing
Out a Distribution List
Finally, all entered settings need be transmitted by the PC to the
SePem devices.
Distribution lists make it easier to obtain a general overview which SePem
device is to be placed where and when for measurements. The distribu-
tion printouts include the information required for placing all SePem
devices at a different location (date and time, installation site, precise
place of the measurement and designation of the hydrants). A sample pattern of a distribution list is included in the appendix.
Distribution lists can be printed out via the Expose devices window
using the Print button. If you do not want to start a printout right away,
an appropriate message will appear after starting the data transmission. You can then start the printout in the displayed message window.
Click on Accept in the Expose devices window. A message
appears on screen.
Click on Yes to start the list printout.
Note:
Always print out a distribution list before placing the
SePem devices!
After the data is transmitted successfully, a corresponding
message is indicated on-screen. During data transmission the
Expose devices window is automatically closed.
8.4 Placing SePem Devices
After having programmed the SePem devices as laid out in the
preceding sections, you can now place them at the desired measurement places. Adhere to the installation instructions and tips
listed in chapter 7.2!
Note:
When placing SePem devices, make absolutely sure that
they are really placed at the prescribed measurement
places. Otherwise mistakes cannot be ruled out. Only
then the data can be evaluated correctly.

9 Power Supply of the SePem Devices
The SePem devices can be used with both - batteries as well as
rechargeable accumulators. Depending on the used type of battery or accumulator, the maximum operating time may vary.
Accumulators must be recharged in regular intervals. This can
either be done using the power supply unit or via a car battery.
Detailed information on the technical specifications of the power
supply can be found in the appendix.
Chapter 2.4 contains information on the in-service conditions.
9.1 Accumulator Operation
Thanks to the integrated accumulator management system it is
practically impossible to overcharge or damage accumulators.
The integrated electronic system monitors the charging process
and switches automatically to charge retention.
It is recommended to recharge the accumulators regularly after
finishing a series of measurements. This ensures that your Se-
Pem devices are always ready to use.
Note:
On delivery the accumulators are not completely
charged! For this reason, charge the accumulators
for 14 hours before taking them into service!
Note:
When charging SePem devices in the carrying case
variant, make absolutely sure that the lid remains
open during charging.
Otherwise the devices will be charged extremely slowly
due to the heat development in the closed case.

The signal indicators inform on:
Status of data evaluation (flashing phases)
Operating status of the accumulators, provided that
accumulators are inserted in the devices
10.3.1 Operating Principle
SePem devices with batteries
After preparing the signal indication (see chapter 10.2), the data
evaluation is lit for approx. 5 seconds. After that, the indication
goes out.
If you need the signals indication again, you must re-connect the
power supply (by pulling the connector first, then replugging it).
SePem devices with accumulators
After preparing the signal indication (see chapter 10.2), the data
evaluation is displayed for approx. 5 seconds. This is followed
by a pause of approx. 3 seconds, i. e. all LEDs go out. After that,
the charging status of the accumulators is indicated continuously.

11.1.1.10 Interpreting trend curves for different display types
The following section includes information which may help you to
interpret measurement details correctly. Two illustrations are
available for each display type: one with leakage and one without.
Note:
All illustrations included in this chapter refer to meas-
urements with the noise sensor. If other sensor
types are used the trend curves may either look completely differently or are not available.
Time display for noise sensor
Time is represented on the x axis, The y axis is provided with a
measurement value scale. Users can assign the indicated signal
peaks to specific events.
A constantly present noise level (significantly larger than zero)
may indicate a leak (fig. 40).
If the constantly present noise level is close to the zero level, it is
less likely that a leak has occurred (fig. 41).
Short, high-level noise signals indicate, for example, cars which
are passing by or water being drawn off by a consumer.

Fig. 40: Measurement data as a chronological function – high leak probability
Fig. 41: Measurement data as a chronological function – low leak probability
11 Menus and Functions of the SePem Software
Page 80
78
Intensity display for noise sensor
Time is represented on the x axis, The y axis is provided with a
measurement value scale. The measured levels are sorted
according to their sound volume.
If the trend curve runs flat, only few interfering noise signals have
occurred. The steeper the curve, the more interfering noise signals
(e. g., cars which are passing by or water being drawn off) were
detected.
A high starting point of the curve (t = 0) on the y axis indicates a
permanent noise level, and thus also a leak (fig. 42).
If the starting point of the curve (t = 0) on the y axis lies close to
zero, the leak probability is small (fig. 43).

Fig. 43: Intensity display of the measurement – low leak probability
11 Menus and Functions of the SePem Software
Page 82
80
Histogram display for noise sensor
If the measurement data is displayed as histogram, the frequency
of every recorded level signal is represented as percentage values.
Time is represented on the x axis, percentages on the y axis.
The shape of the signal level indicates the quality of the
measurement:
good measurement:
small gaps between level values = narrow cone
bad measurement:
large gaps between level values = wide cone
The leak probability depends on the distance between minimum
level and zero point. The minimum level is defined as the smallest
measured value represented in the percentage display (i. e. at
the left edge of the trend curve). Outliers, i. e., individual small
peaks deviating from the actual curve, are not considered in this
case.
The leak probability is high if the gap between minimum level and
zero point of the x axis is large (fig. 44).
If the minimum level lies close to the zero point of the x axis, the
leak probability is small (fig. 45).

Page 84
82
Frequency spectrum display for noise sensor
This display type is used to reproduce the measured audible
signals as a FFT function (FFT = Fast Fourier Transformation).
The sound is analysed and broken down into individual sine tones.
This means that, unlike at the other display types, not the sound
volume, but the recorded sound as such is analysed.
The y axis represents the sound volume (relative values), the x
axis the frequency.
If the curve has a wide, uniformly increasing/decreasing shape
above the background noise, it is highly probable that the (entire)
noise represents a leak (fig. 46).
If the curve, on the other hand, contains individual narrow peaks
which are deviating extremely from the baseline, a leak is not
very likely (fig. 47).

11.1.2 Editing measurement places and comments
Measurement places and comments are used to describe
measurement data in detail. They can be entered or deleted
without independent from the relevant measurement places and
comments.
You can therefore manage all measurement places or comments
separately, so that you only need to assign them to the
measurement data (see chapter 11.1.1.7).
In the menu bar, click on File – Handle measurement places
and comments. The Edit measurement places and comments window appears.
Fig. 48: Edit measurement places and comments window
The window has two separate tabs (Measurement place, Com-
ment). Click on the desired tab to open it. Function-wise, both
tabs are similarly structured. All measurement places and/or
comments which were already entered are listed on the appropriate tabs.
Then, close the window with OK. All changes are stored.

11.1.3 Repairing the database
All measurement data records are stored in the SePem database.
This database can be compressed and repaired in a single
step.
The repair function is particularly useful when a system error
occurs during storing or loading the database.
Note:
If the SePem database contains a high number of
measurement data records, you can reduce the access time by compressing the measurement data.
In the menu bar, click on File – Repair and compress data-
base. After a short time a message appears on screen that the
database was compressed and repaired successfully.
Confirm with OK.
11.1.3.1 Repairing the database using the program’s properties

The list printout provides a compact, precise overview of the
selected measurement data. The list view is similarly structured
as the Show measurement data window (fig. 31). The number,
order and width of columns is freely selectable.
Note, however, that the selected paper format definitions (see
chapter 11.1.6) also determine the available space for the list
printout. This means that the number and width of columns may
be particularly affected.
Click on the Fields button. The Field selection window is
opened.
Fig. 52: Field selection window
Each line of the table represents an available field. If a tick is
set in the Activate column, the appropriate field will appear as
a column in the printout.
You can change the activation status, order and field width of
the individual fields.
Double-click on the line which you want to edit.
The Change field selection window appears.
Perform the desired changes. Note that you may need several
runs to optimise the field Width (i. e., width of the column) (start
a sample printout or check the layout in the preview window).
Click on Accept.
Configure the list printout according to your requirements and
close the Field selection window with OK.

11.1.6.2 Detail printout
In detail printouts only a single measurement is represented per
page.
Select the type of graphic under Show (time, intensity, histo-
gram, frequency spectrum) to be used in the printout.
The graphics will be printed out as shown in Show measure-
ment data – Details window.
Conventions in the settings area
Select the Scale display automatically check box when the
graphics are to be printed out with optimised trend curve (=
zoomed in).
Select the Use complement colors check box to ensure that
the graphics are printed out conforming to the screen settings.
Example:
The graphics are indicated on the screen as yellow trend curves
against a black background. If you select the complementary
option, the colors are reversed (i. e. blue trend curves against
a white background). The curves are easier to view on the printout and the printer consumes less ink.
Select the Print display type check box if the type of graphics,
which was selected under Show beforehand, is to be printed in
the right top corner.

not too wide, in particular when you want to print out lists.
Select Horizontal as alignment type if your printout contains
many columns.
Click on the Printer button when you want to select another
printer than your default printer for printing.

11.2 The Devices menu
The Devices menu comprises the following functions:
Prepare (SePem devices) for measuring
Adjust device settings
Read measurements
Start diagnostic
11.2.1 Prepare for measuring
Before placing SePem devices ”on the spot” (i. e., the
measurement location), you need to prepare and program them
appropriately. Define when, how long and in which intervals
measurements are to be performed. Use the SePem software to
set these steps. The information is then transmitted to the electronic
units of the individual devices.
In the menu bar, click on Devices – Prepare for measuring.
OR
Press function key F9 on the keyboard.
This starts the automatic data transfer between SePem Soft-
ware and devices. The software checks the actual state of the
devices which are currently inserted in the charging adapter.
During the transfer a window is shown informing on the progress
of transmission.
Fig. 53: Progress of the data transmission
Then, the Expose devices window appears.

The table includes all SePem devices recognized by the SePem
software. This table is structured as a list of measurements.
The following applies to this measurements list:
Number of entries = Nr. of devices x Nr. of measurements
Note:
The values indicated in the measurement list remain valid
for all measurements until they are changed !
Preparing the SePem devices for exposing comprises the following
steps:
Defining measurement times
All measurements are based on a measurement time scheme.
Configure this scheme according to your requirements.
Proceed as described in detail in chapter 8.3.2!
Ch. 11.2.1.1 includes an overview of all adjustable parameters of
measurement time schemes.
Assigning a measurement place
Project names and specifications on the measurement place
(e. g. place, street, hydrant number) help you to set up a plan
for placing the devices and to manage the measurement data.
Proceed as described in detail in chapter 11.1.1.7!
