Swiss water leak detection solutions company Gutermann has released Zonescan narrowband internet of things (NB-IoT), the world’s first water leak detecting noise logger to permanently monitor water distribution mains.
Successful pilot projects using the Zonescan NB-IoT have been carried out in France, the U.K. and Australia.

NB-IoT is a new cellular communication standard optimized for machine-to-machine data communication. The technology outperforms conventional 3G and 4G technology used in earlier generations of acoustic loggers, and uses five to 10 times less power with improved underground coverage.
Zonescan NB-IoT is a correlating system, which means that the cloud-based Zonescan Net software automatically compares the data of all neighboring sensors every day to identify even quiet leaks whose existence are not recognized by individual loggers. A correlation indicator provides information about the area in which the leak has been identified, neatly displayed on a Google Maps-enabled user interface. The system also lets users see and manage their leak detection infrastructure, perform advanced leak analysis, import and display their GIS data, and change settings such as recording times, alarm thresholds and more.
The NB-IoT leak logger was officially launched on December 4, 2019, on the first World Water Loss Day, which was initiated by Gutermann and the IWA Water Loss Specialist Group.
