The design is particularly aimed towards static operation, i.e. for use in continuous monitoring of water pipe networks at fixed measurement locations over long periods of time (several years). The system can also be used for mobile monitoring applications. The SePem 01 Master programming and read-out unit allows the system to be operated without the need for a personal com-
puter. SePem 155 is designed exclusively as a prelocation system. Indications by the system that a leak is present must therefore always be verified using an appropriate method
(e.g. correlation). Unlike the SePem 02 system, the SePem does not use a modular construction. 1 2 General information General information z z Warranty The following instructions must be complied with in order for any warranty to be applicable in respect of the functionality and safe operation of this equipment.

z SePem155 Logger, abbreviated to Logger (see Sect. 4) for the collection of measurement data z SePem 01 Master, abbreviated to Master (see Sect. 5) for reading out and evaluating measurement results and for programming the Logger A single Master can be used to manage 400 Loggers. A wide range of accessories is available for both Loggers and Ma-
sters. Mobile operation as an alternative to static operation The aim of static applications is to provide permanent monitoring over a large area, whereas mobile applications of the SePem are aimed at regular checks carried out over smaller areas. Mobile operation represents a cost-effective alternative to static operation as only a limited number of loggers are necessary. The loggers will typically be installed for a few days to provide comprehensive coverage in the monitoring area. The measure-
ment data that is recorded can then be read out and evaluated at regular intervals. Monitoring of the area may be completed when leaks are either detected or repaired. The Loggers can then be moved to the next monitoring area. 3 3.1 3.2 6 3 SePem system 3.3 Operating principle 3.3.1 Monitoring procedure (Overview) The SePem operates according to the following principle:
z First, program the Logger (see Sect. 5.7.3) For each individual Logger, establish where it will be used to gather measurement data and at what times. z Install the Logger at the measurement location (see Sect. 4.3) z The Logger now works autonomously, i.e. it collects data at the predefined times. z Read out the measurement data using the Master (see Sect. 5.7.2) The Logger will transmit measurement results at regular inter-
vals within a prescribed period of time. The period of time is referred to as the radio time frame and is specified during pro-
gramming. The operator must transport the Master to within the transmis-
sion range of the Logger. This can either be done on foot or by driving past the measurement location slowly in a vehicle. The measurement results will be transferred automatically from the Logger to Master as soon as the user passes into the transmission range. It is also possible to read out additional information relating to the logger itself and to allow a mode of curve of the measure-
ment (measurement curve) to be produced. z Measurement results can be evaluated immediately, or at a later time, using the Master (see Sect. 5.7.2.2 5.7.2.4, 5.7.4) Note on programming the Logger programming Changes to the programming of a Logger used in a static ap-
plication can be carried in-situ. The Logger does not have to be removed from the installation position. The transmission of the new program data from the Master to the Logger is carried out during the time window. 7 3 SePem system 3.3.2 Radio frequency data transmission The data transmission principle used by the Logger and Master units is the same as when making a call on a mobile telephone. However, there is an important difference in the limitation of transmission range. When it installed in a pit, the Logger will have to transmit its data out of that pit. The range of the radio signals is heavily dependent on the shielding effects of the shaft, especially the cover. As a general rule, the radio signals can be expected to have a range of 30 70 m (98 230 ft) from the installation position. The range may be extended up to 100 200 m
(328 656 ft) for plastic covers. The theoretical maximum range is 1000 m (3280 ft). 3.3.3 Principles of leak detection Depending on whether it is used as a static or mobile system, the SePem utilises different evaluation techniques to inter-
pret the measurement results to establish whether or not a leak is present. Note:
Leak alerts will not be given if there is background noise (Frequency 60 Hz or 120 Hz). Please refer also to the information on interpretation of measurement results and leak alerts in Sec-
tions 5.7.2.3 5.7.2.5. 3.3.3.1 Leak detection with mobile operation In order to determine if the measurement data recorded by a Logger used as a mobile unit relates to a leak or not, the Master makes use of a defined alarm threshold (absolute value). If the minimum level measured is below the predefined threshold value then the operator will be alerted to a leak. The level that is set for the alarm threshold will depend on the material of the pipe in the vicinity of the Logger. It is therefore possible to set the alarm threshold in the Master individually for each Logger. 8 3.3.3.2 Leak detection with static operation 3 SePem system When used in a static application, the leak detection method em-
ployed by the SePem is based on a mathematical relationship that compares measurement values at different points in time
(detection of variations). The following points must be taken into consideration when evaluating results:
z The water pipe network must be leak-free before setting up any SePem units for static use. z Only leaks that occur after the monitoring has been started will be detected. z A leak alert will only be issued after three measurements have been made since the first occurrence of the leak; this avoids false detection of leaks due to short-term fluctuations. z It is possible that false leak alert may be issued (e.g. after pro-
longed heavy rain). 9 4 SePem155 Logger Logger SePem 155 Functionality and construction The SePem Logger is a sound level logger. It is able to col-
lect data from water pipe networks and to store this data. Data is exchanged with the Master unit using a built-in radio module. The robust, waterproof, injection-moulded aluminium housing means the Logger is suitable for permanent installation under manhole covers and in hydrants. The unit can be mounted on metal objects using a magnet. If it is necessary to monitor a plastic pipe then the Logger must be attached to the fittings. An illustration of the Logger with all parts labelled is provided on the inside front cover. The power supply is provided by a permanently installed lithium battery that has a guaranteed lifetime of several years under normal operating conditions. (Normal operating conditions cor-
respond to the settings stored in the SePem 01 Master under Standard logger configuration (see Sect. 5.7.3.7) ) CAUTION!
The SePem155 Logger must never be opened by the operator. The unit will be prone to leakage if opened. Expired batteries must be replaced by SEWERIN Service. There is a risk of explosion and/or poiso-
ning if batteries are changed incorrectly. 4 4.1 10 4 SePem155 Logger 4.2 Specifying a device number (optional) Every Logger is assigned an 11 digit serial number by the manu-
facturer before shipping. In order to simplify the job of adminis-
tering the Loggers (in the Master software and at the measure-
ment location) it is possible for each unit to be assigned a device number. Any number may be selected, up to a maximum of four digits. This number could, for example, be the same as the last four digits of the serial number. z It is advisable to decide on a format that can be used as the device number for all Loggers. Each The device numbers must be saved with the corresponding serial number in the Master (see Sect. 5.7.4.1). Logger should be labelled with the device number. z z 11 4 SePem155 Logger 4.3 Installing the logger at the measurement location 4.3.1 Suitable installation locations The Logger can be mounted on:
z Piping z Fittings (slide gates, underground hydrants, above-ground hydrants) Note:
Only attach the Logger to above-ground hydrants if it is possible to protect the device against theft and vandalism. The units can be install in water pipe networks constructed from both metal and plastic piping. Please note the following points relating to plastic water pipe networks:
z Logger cannot be mounted directly on the pipe, instead it The has to be attached to a fitting Sound is not transmitted as well as in metal pipework sys-
tems. z 4.3.2 Distance between two Loggers (recommended) The following spacing between each Logger is recommended to allow systematic monitoring of an area:
Water pipe material Metal Logger location Fitting Plastic Fitting Recommended distance between Loggers 300 500 m (984 1640 ft) (mobile) 500 m (1640 ft)
(static) 50 100 m (164 328 ft) For highly intermeshed water pipe networks the spacing between Loggers must be decreased appropriately. 12 4 SePem155 Logger 13 14 4 SePem155 Logger z Check carefully to ensure that all contacts are clean and dry before screwing in the aerial / aerial adapter. z The aerial/aerial adapter must be tightened firmly by hand as until the end stop is reached. This is necessary in order to ensure that the unit is properly leak-tight and that a good radio signal is guaranteed. CAUTION! Risk of damage!
Never use any tools to assist in tightening the ae-
rial / aerial adapter. This could lead to damage to the internal contacts. 15 4 SePem155 Logger 4.3.3.2 Initial programming of the Logger Before installing the Logger at the measurement location it must be programmed, i.e. data relating to measurement times, mea-
surement duration and the radio time frame must be transferred from the Master to the Logger. Radio contact between the two devices must be established to carry out programming. z First, the Master must be prepared for programming the Log-
ger (see Sect. 5.7.3, particularly 5.7.3.4). z Move a magnet (e.g. the magnet on another Logger) over the magnetic switch on the Logger to be programmed. The LED will start to flash twice a second. The Logger is now in receive mode. The Logger will remain ready to receive information for one minute after activation. z Move the Master into the transmission range of the Logger. Transfer the data (see Sect. 5.7.3.6). If contact is not established between the Master and the Logger within the available time frame then the Logger will automatically switch off and must be reactivated as required. Note:
If the device settings for the Logger are changed in the course of further work then the radio time frame can be utilised for the transfer of the relevant data. The Logger does not have to be activated manually every time. 16 4.3.4 4 SePem155 Logger z Correct installation of the Logger The Logger is fixed into position at the installation location us-
ing the magnet (Note: follow instructions in Sections 4.3.1 and 4.3.2). If an aerial adapter is used then the aerial must also be mounted using the magnetic attachment. It is important in all cases that installation is carried out very carefully, especially when posi-
tioning the aerial. Please note the following points:
z good metal-to-metal contact is formed between the Logger by the aerial; this can cause dam-
Never carry age to the aerial. Ensure that a the Logger magnet and the body to which it is attached. It is important that structure-borne sound is not damped by dirt, mud or rust. Clean the attachment point if necessary before mounting the Logger. Logger to make good contact Although it is necessary for the with the attachment point, it is essential that the aerial does not come into contact with the surrounding environment. When the aerial adapter is used, ensure that the magnetic at-
tachment is positioned so as to ensure that a good distance is maintained between the aerial and any metal items at the installation location. Logger should preferably be installed with the The tip of the aerial pointing downwards in the shaft. One reason for this is that there is usually more space for the aerial pointing downwards than immediately below the cover. The other reason is that a better radio connection can be achieved when the radio signal radiates into the earth rather that the manhole cover. aerial must not be bent or shortened. The available The space should be evaluated to ensure that the aerial will remain straight and will not come into contact with any other object after the shaft cover is closed. z z z 17 5 SePem 01 Master SePem 01 Master Functionality and construction The SePem 01 Master is the programming and read-out device for the SePem155 Logger. The following tasks can be performed using the Master:
z Programming the Logger z Reading out measurement data and device data from the Logger z Evaluating the measurement results (including mode of curve) z Changing Logger data An illustration of the Master with all parts labelled is provided on the inside front cover. The Master can settings can be changed according to personal preferences (e.g. language, contrast of the display). The aerial on the Master guarantees that reliable radio com-
munication can be established between the Master and the Log-
gers. This is important because all measurement data, device data and programming data for the Logger is transmitted using radio signals. The supporting bracket can be used for carrying the unit and as a stand. The supporting bracket can be adjusted to different positions. With the bracket turned to the rear of the unit, the Master can be stood up safely in a convenient position for read-
ing the display. The duration for which the display is illuminated can be adjusted. The light will come on whenever a key is pressed or the jog dial is moved (except when battery is almost discharged). The Master stores all measurement results in a circular buffer, i.e. if the memory is full (no free storage space) then the oldest data will be overwritten by the most recent. The unit will generate a warning to alert the user that memory is low. 5 5.1 18 5 SePem 01 Master Accessories (optional) When the Master is carried in a vehicle, the TG8 Docking Station can be used to provide a safer means of operating the unit. If the Master needs to be carried on the person during operation, then the Vario Carrying System can be fixed to the attachment points on the supporting bracket. 19 5 SePem 01 Master Power supply There are various power supply options available for the Master:
z z z Disposable batteries (4) NiMH rechargeable batteries (4) External power from mains or vehicle battery. Note:
The Master does not include an integral battery charger. If rechargeable batteries are used then these must be removed for recharging in an external battery charger. Batteries CAUTION!
The Master must only be operated with rechargeable batteries if they are of a type approved by SEWERIN
(see Sect. 7.6). The use of other rechargeable batteries is not permitted. It is advisable to switch the unit off when not in use to extend op-
erating time when the device is powered by batteries. 5.2 20 5 SePem 01 Master External power supply External power supply options:
Power source Required accessory Use power supply Mains socket M4 AC/DC Adapter TG8 Docking Station and M4 AC/DC Adapter connection on... Master TG8 Docking station Vehicle battery TG8 Docking Station and M4 Vehicle Cable TG8 Docking station CAUTION!
Only use the M4 AC/DC Adapter from SEWERIN
(see Sect. 7.6). The use of other AC/DC adapters is not permitted. 5.3 The M4 Vehicle Cable is available in various configurations. Use of the Master in a moving vehicle If the Master is used in a moving vehicle for collection of data and/or programming of Loggers then the aerial can be replaced by a magnetically attachable aerial that can be fixed to the roof of the vehicle (optional accessory). This will improve the quality of the radio reception. It should be noted that the unit will drain power from the vehicle battery when the engine is not running if this is used as an exter-
nal power source for the Master (using the TG8 Docking Station and M4 Vehicle Cable). The Master should therefore always be switched off when not in use. 21 5 SePem 01 Master Replacing the batteries Please refer to the information in Section 5.2!
A 2.5 mm (0.1 in) Allen key (supplied) is required to open the battery compartment. z Loosen the two screws securing the battery compartment. Re-
move the screws by repeatedly turning them alternately a short way; this ensures that the cover does not jam. Lift off the cover. Remove and replace the batteries (disposable or recharge-
able). Ensure that the batteries are inserted with the correct polarity. Replace the cover so it fits neatly into place and attach firmly with the screws. z z z Note:

The overview will usually be an empty list at the start of a patrol because the list is automatically deleted from the overview and moved to the patrol list when the unit is switched off. Pressing the F1 Missed log key displays a list of Loggers that have not yet been read during the current patrol (provided they have been entered into the database previously). 28 5.7.2.1 Requirements for a successful patrol 5 SePem 01 Master is switched on, menu item Patrol is open Master are within the radio transmission z z z Master The operator and the range of the Logger The radio time frame for the is in ready-to-send mode Logger is open, i.e. the Logger Note:

A sound level that is continuously much higher than zero may indicate the presence of a leak (Fig. 10). Fig. 10: Measurement curve showing a high probability of a leak If the sound level is continuously close to zero then the prob-
ability of a leak is low (Fig. 11). Short, high peaks (spikes) may indicate, for example, a passing vehicle or water being withdrawn for a short period. Fig. 11: Measurement curve showing a low probability of a leak 5.7.3 Logger communication The menu item Logger communication is used to control the exchange of data between the Master and the Logger. This allows the operator to select between measurement results and Logger data, and whether a Multiple Logger or a Single Logger should be programmed. The process of transmitting Logger data and the standard set-
tings are described in Sections 5.7.3.6 and 5.7.3.7. 35 5 SePem 01 Master 5.7.3.1 Logger data features Logger data is either:
z Master (e.g. radio times and measurement Specified in the times) or Stored internally in the unit (e.g. next service due, firmware release). z Radio times and measurement times must be transmitted to the Logger, which results in the Logger being programmed.

figured and programmed, however the Single Logger menu also allows:
z z Measurement results and Logger data to be read out Online measurements to be carried out. 5.7.3.4 Multiple Loggers (Logger configuration) The menu item Multiple Loggers goes directly to the LOggEr cONfIgurAtION menu. This includes the options Measurement times, radio times, and Miscellaneous. Once entered, the settings can be sent to any desired number of Loggers (see Sect. 5.7.3.6). Please note the following configuration tips:
z Measurement times, radio times and The windows Miscellaneous are ordered one after the other (turn the jog dial). The magnitude of the values set has an influence on the life-
time of the Logger battery. Long radio times, short intervals, etc. reduce the lifetime. If values are chosen that are invalid or are not permitted then these cannot be transmitted. They will be automatically cor-
rected. z z 37 5 SePem 01 Master Measurement times The settings under Meas. times determine how and when a Logger will record measurement data. LOggEr cONfIgurAtION Meas. times Start in z z

Online measurement is typically used during mobile monitoring. This is useful for providing feedback on the sound levels detected by the Logger immediately after installation. If the level is close to zero then it will not be necessary to monitor the installation loca-
tion with a static unit. The Logger can be removed immediately and reinstalled at another location. Usually, measurement values are calculated every second. All measurement values are immediately displayed on the plot. The F2 Stop key can be used to stop the measurement in order to view the measurement curve. (Note: The measurement cannot be subsequently restarted.) Pressing F3 Back will cause the online measurement to be stopped. Please note the following points:

The measurement interval selected (
tion > Meas. times > Interval) specifies the length of time between each measurement that is recorded, and there-
fore determines the speed at which the measurement curve is updated. If an online measurement is running at the same time as a predefined measurement then the scale of the time axis will depend on the measurement interval. z 43 5 SePem 01 Master 5.7.3.6 Transmitting data to the Logger To transmit the measurement times and radio times chosen to the Logger always use the f1 transmit option from the Logger configuration window.

Loggers Programmed (only with Multiple Loggers) After data has been transmitted to Multiple Loggers the LOggErS PrOgrAMMED screen will be displayed. 45 5 SePem 01 Master Fig. 13: Loggers programmed A list of all Loggers that have been programmed since switching on the Master will be displayed. The list may also contain Loggers that were programmed using the Single Logger option prior to using Multiple Loggers. The Loggers will be listed alongside the selected Logger ID
(e.g. Location) and sorted according to the time they were programmed. In the top left corner is a counter showing the number of Loggers and the number of Loggers recognised by the Master (see Logger database) - (2/5 in the example means that 2 Loggers were programmed and the Master has a database containing 5 Loggers). Note:
When the Master is switched off the list of Loggers will be deleted. The F1 unprogrammed option displays a list of the Loggers that have not been programmed since the Master was switched on. This will only display Loggers that are included in the Log-
ger database (see Sect. 5.7.4.1). (This means that new Loggers that have not yet completed a data transfer will not be shown in the list.) 46 5 SePem 01 Master 5.7.3.7 Standard settings The Master has a set of standard settings for the Logger con-
