At this week’s North America Water Loss exhibition in Nashville, Swiss firm Gutermann launched what it claims is the world's first NB-IoT-based water leak detection technology.
The Zonescan NB-IoT is a noise logger for permanent monitoring of water distribution mains. Pilot projects have already been concluded in France, UK and Australia.
NB-IoT is a cellular communication standard optimised for M2M data communications in smart cities. It is said to outperform conventional 3G and 4G technology, as it consumes five to ten times less power and has improved underground coverage. Telecom operators worldwide have announced plans for complete NB-IoT coverage and are in the process of activating their NB-IoT antennas throughout their networks.
Zonescan NB-IoT is the company’s first cellular logger and complements the company's RF-based Zonescan Alpha, which has established itself as a fixed network technology and is used in more than 300 cities around the world.
The NB-IoT version is a correlating system that means that the cloud-based Zonescan Net software automatically compares the data of all neighbouring sensors every day to identify even quiet leaks whose existence are not recognised 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. Zonescan Net also lets users see and manage their leak detection infrastructure, perform leak analysis, import and display their GIS data, and change settings such as recording times and alarm thresholds.
"We are excited about the launch of this product because we see an enormous potential for it given the connectivity and power properties of the NB-IoT technology,” said Lucas Grolimund, CEO of Gutermann. "We're happy to once more lead the way in advanced fixed network leak monitoring. Our hope is that the Zonescan NB-IoT logger will make permanent monitoring of networks more accessible to utilities due to its cost, ease of installation and compact design. It should therefore contribute to the rapid growth of technology-enabled smart water networks, helping to consistently reduce and maintain lower water loss levels."
Gutermann has its headquarters in Baar, Switzerland, R&D and manufacturing sites in Germany, and regional offices in France, UK, USA and Australia.
