Noise logger for monitoring water pipe networks: sturdy – convenient – reliable
 

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 any number of data loggers; the SePem® 100s are preferable for mobile use whereas the SePem® 150s are designed for permanent use. They 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.

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.
