        Detect water losses early

        Leaks in water pipe networks can result in significant water losses. Thanks to systematic monitoring of the network with SePem® data loggers, you can reliably identify existing leaks and catch new ones early on – much faster than with conventional methods.

        Systematic leak detection

        The SePem® system comprises the SePem® 01 Master receiver as well as the SePem® 155 data loggers. They are designed for mobile and permanent use. The SePem® 155s are magnetically attached to valve rod extensions, or to hydrants or other fittings in the pipe network. The microphone integrated in the logger converts the structure-borne noise in the line to a sound signal. This is cyclically recorded during times of low consumption – usually during the night between approx. 2:00 am and 4:00 am, when there is very little sound interference in the surrounding area, if any. On a leak-free line the noise level measured during this time is virtually zero. If there is a leak in the pipeline, the noise logger will measure values much different to zero, thus indicating a leak.

        Data loggers for mobile use

        The SePem® 155 data loggers are perfect for mobile use in the water pipe network. They are placed on fittings at measuring points in a specified section of network and record the level for a programmable period of time during the night – usually half an hour. The loggers are collected in the next day. The measurement data is transmitted to the SePem® 01 Master by radio. Noticeably high measurement values indicating a leak are immediately flagged up by an audible signal. This is a reliable way of detecting existing leaks. The data loggers are then successively inserted in other sections of the network until the whole network has been checked.

        Sturdy technology you can rely on 

        • The data loggers feature the high protection class IP68. The housing is made of stainless steel and a special, tried and tested plastic, which is also used, for example, in the housing of pumps used in sewage treatment. This makes the SePem® 155s totally waterproof and dust-proof, resistant to all corrosion and other stresses and suitable for use in all environments.
        • With a battery life of many years, the SePem® 155s are operational for a long time and are equipped for any task. 

        Reliable and efficient 

        • The SePem® 155 data loggers feature highly sensitive Piezo microphones, which are specially optimized for leak detection and can pick up noises over very large distances.
        • The data can be read out easily by bidirectional radio. In the case of the permanently installed loggers, you do not need to open the covers; simply drive by with the SePem® 01 Master to record the data.
        • As well as the minimum level, the transmitted telegram contains the width and frequency of the noise and is clearly displayed on the SePem® 01 Master screen. There are additional options for verifying the measurement results, for example by precluding sound interference such as rain, traffic, power lines etc.
        • During the patrol, a full data set containing the plot of the last measurement can also be retrieved at the touch of a button from every SePem® 155 logger in addition to the data telegram. Again, it is not necessary to open the manhole cover to obtain all of this data. A brief pause within the radio range of the SePem® 155 is sufficient. 

        Convenient to use 

        • The online measurement function allows you to take current measurements on site which can be displayed on the SePem® 01 Master. For example, this means that you can check the suitability of measuring points during the day at the time of installation before the actual measurement at night or determine appropriate installation intervals. Or you can verify the plausibility of measurement data collected overnight directly on site.
        • The measuring times and periods of radio activity are freely programmable.
        • The SePem® 01 Master, with its simple and intuitive menu navigation, provides fast and reliable results and can also be reliably operated by less experienced users.

        10 Logger Starter Kit

        The STARTER KIT contains everything you need to get started, including one Master reader/programmer, 10 loggers, 10 retrieval lanyards, and hard case. Additional loggers can be added to over 400 per Master. Multiple Master's can be used for reading over 400 loggers, and additional loggers are available separately. With just a 10 logger starter kit, you could survey over 3 miles of pipe per night, or 15 miles in a 5 day work week.
