The FMCW radar level transmitter for liquids in narrow tanks with
internal obstructions
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.
Large measuring range from the antenna up to 100 m / 328 ft
Small beam angle due to 80 GHz and process connections starting from 3⁄4 ̈ thread PEEK Lens antenna insensitive to deposits
Highlights
-
Accuracy: ±2 mm / ±0.08 ̈
