Water utilities are under growing pressure to reduce network losses and locate leaks at an early stage. With the SePem® 352 noise logger, you continuously monitor defined network zones. The loggers automatically transmit measurement data via LoRaWAN® to your network monitoring system or to the SePem® web app. This allows you to reliably identify suspected leaks and follow them up in a targeted way. The result: faster leak detection and more sustainable operation of your drinking water network.

The VARIOTEC® EGA is a portable, easy-to-use measuring device for ethane gas analysis that allows you to reliably and accurately determine the gas components methane, ethane, and propane. It enables quick and clear differentiation between natural gas and swamp gas directly on site, avoiding costly and time-consuming excavations and laboratory analyses. Thanks to clear user guidance, integrated measurement technology, and high sensitivity, the device delivers reliable results even at very low gas...

SEWERIN's fiber optic probe systems enable the precise location of non-metallic pipes - even under demanding conditions. The copper strand integrated into the fiber optic rod allows the exact route of the pipe to be determined using the UT 9200/9100/930 and UtiliTrac locating systems. Supplemented by different locating transmitters, the end points of the fiber optic probes can be detected with pinpoint accuracy at depths of up to 18 m. Whether locating gas, water or wastewater pipes - the fiber...
