Reference: Monitoring underground water levels in manholes in Stavanger and Porsgrunn, Norway
Stavanger and Porsgrunn monitoring underground water level in manholes with Sensoneo ultrasonic sensors
Sensoneo smart sensors have proven their another functionality in two Norwegian cities Stavanger and Porsgrunn where they are monitoring underground water in manholes. Legislation in Norway states that every municipality has the obligation of controlling of the flood level of their underground water.
Monitoring of thresholds was not enough in this case, as the municipality needed a continual evaluation in real-time and that is the reason why they have decided for the smart sensors solution. So far, 185 of sensors have been distributed to Sensoneo reseller partner in Norway and are being installed into manholes with a long-term evaluation of results. Connectivity in this project works via both LoRaWAN and NB-IoT networks.
