This device is an 80 GHz FMCW-radar level transmitter. It is a non-contact technology and is 2- wire loop-powered. It is designed to measure the distance, level, mass, volume and reflectivity of liquids, pastes and slurries.

Radar level transmitters use an antenna to emit a signal to the surface of the measured product.
The device has many antennas available. Thus, it can measure most products even in difficult conditions.
