Contactless sonar measurement
The LevelR measures the water level acoustically and never touches the water. No calibration or air pressure compensation is required.
Straightforward installation
Real-time data and alerts
Users receive automatic alerts as soon as the level passes a configured threshold, with 24/7 online insight.

LevelR: Contactless water level sensor for monitoring pipes
The LevelR measures the water level inside a monitoring pipe using contactless sonar, making manual dipping unnecessary. As no calibration or air pressure compensation is needed, installation is simple and maintenance is minimal. Data is sent via LTE-M to the MonitoR platform and can be buffered locally for several days in the event of connection loss. Combine the LevelR with the CrackR and the TiltR to see in a single dashboard how the level relates to movement in the surrounding structure.

All measurements together in MonitoR
The LevelR sends its measurements straight to MonitoR, StabiAlert's online platform. There you can follow the water level alongside the data from your other sensors, set thresholds and alerts, and export your data or retrieve it via the API. Available on desktop and mobile, 24/7.
