Description
Due to its flush-mounted PEEK Lens antenna with a very small beam angle, this FMCW radar is the optimal choice for continuous, non-contact level measurement involving narrow small or high tanks with internal obstructions. Insensitive to deposits or corrosive environments, this marine level transmitter is equally suited for oil or other liquids, slurries and pastes as well as solids.
