Level Sensors

NivuLink RadarNew

Part No. NLR

Self-sufficient level sensor with integrated gateway for data transmission.

Intelligent, battery-operated IoT level sensor with state-of-the-art radar measurement technology. Complete device - sensors, batteries and transmission in a robust housing. NB-IoT / LoRa transmission possible.


Precise level measurement with innovative radar technology

The battery-operated, compact level radar with integrated data transmission expands the NIVUS portfolio with a simple, reliable and durable solution. Based on our high-precision radar measurement technology, the sensor offers an exceptionally long service life even with the shortest measurement cycles every second. For example, we achieve a service life of 15 years with one measurement per minute and one data transmission per hour.

Reliable event detection

Never miss an event again. The level radar has an integrated event mode that notifies you immediately of relevant levels or changes.

Flexible data transmission and management

Data is transmitted securely and reliably via the mobile phone network. Both the data management and parameterisation of the sensor can be carried out conveniently from a laptop or smartphone via the intuitive NIVUS WebPortal.

Versatile use for a wide range of requirements

The battery-operated level radar is suitable for a wide range of applications, from self-sufficient level measurement in rivers to level detection in rainwater overflows, reservoir channels and heavy rain early warning systems.

The status LED enables the system to be quickly assessed on site. State-of-the-art OTA programming and cloud connectivity. Event-based storage and transmission cycles enable a balanced ratio between data density and battery life.

High flexibility for challenging measurement places due to additional external antenna.
