6 years. Almost no maintenance.

/

In June 2020, we installed a DL-MBX | Ultrasonic Distance / Level Sensor for LoRaWAN® at our site in Dübendorf, Switzerland. Batteries in, mounted, done.

We haven't touched the device since. Six years later: measurement quality still "Good". The data clearly shows seasonal water level patterns — and one peak stands out. In June 2024, severe flooding hit Switzerland, causing 905 million francs in damage. Lake Zurich reached danger level 4. Our sensor captured it all in real time.

No recalibration. Just six years of continuous, reliable data.
