Radar Level Transmitter for Water and Other Liquids in Narrow Tanks with Obstructions

The Schneider Electric 80 GHz Radar (FMCW) Level Transmitter for liquids in narrow tanks with internal obstructions.

This device is a non-contact radar level transmitter that uses FMCW technology. It measures distance, level and volume of liquids and pastes. It has an empty spectrum function that filters false reflections caused by equipment inside the tank.
