In-Situ Level TROLL NC Non-Contact Radar Level Sensor
The Level TROLL NC is a high-performance, 80 GHz FMCW non-contact radar sensor for precise water level measurement in surface water, dredging, and coastal applications where a submerged instrument isn't practical. It integrates into In-Situ's shared ecosystem with a standard twist-lock connector, native SDI-12 and Modbus RS485 output, and the VuSitu mobile app for setup and data collection.
A narrow 5° beam angle — needing just a 1 m (2.4 ft) diameter clear zone at 11.5 m (25 ft) range — gives you more flexibility to install in tight spaces than wider-beam radar sensors. In VuSitu, you can view the live echo curve to check signal return, fine-tune the Active Zone, and adjust Peak Detection for cleaner readings, plus confirm mount tilt with color-coded indicators. Built to withstand harsh weather for long-term, low-maintenance monitoring.
Note: The Level TROLL NC needs a TROLL Com Plus or VuLink telemetry (lithium batteries only, one instrument max) to power data collection. Mounting bracket sold separately.
