Zone monitoring


Our partner, Gutermann, is a world leader in leak detection technology!

ZONESCAN NB-IoT is a revolution in intelligent water loss management technologies.
Correlating leak noise logger for permanent monitoring of water distribution mains using automatic NB-IoT cellular data upload to a cloud software.

Data connection from deepest shafts

ZONESCAN NB-IoT is the world’s first water leak detecting noise logger based on Narrowband Internet of Things (“NB-IoT”).
This is a new LTE-based cellular communication standard optimised for machine-to-machine data communication in smart cities.
NB-IoT significantly outperforms conventional 3G/4G communication standard for leak detection applications.


  • Significantly lower power consumption (5-10x less), resulting in a longer battery life
  • Significantly improved coverage underground (deep coverage)
  • Much lower communication costs

Easy installation

Installing (and subsequently moving) an NB-IoT logger has never been easier. The Android app ZONESCAN INSTALL will guide you through the process of logger activation.
An antenna jig with USB port allows you to connect the logger to your Android device for direct access.
Once deployed, a regular extended antenna is connected to the logger and attached magnetically underneath the lid.
Loggers are deployed in intervals of typically between 50 and 300 meters, depending on the deployment area and the pipe properties.
