The OPTIWAVE 5400 is a 2-wire 24 GHz radar (FMCW) level transmitter for liquids in basic process applications. It is particularly designed for continuous, non-contact level measurement in the chemical, petrochemical, power as well as oil and gas industry. It can be equipped with a PP Drop antenna for condensing atmospheres and corrosive media but features also Metallic Horn antennas. Due to its high dynamic range, the 24 GHz radar can measure distances up to 100 m / 328 ft.
