KROHNE, Inc. announces a new generation of liquid and solids level measurement products. The product families include both 24 gigahertz (GHz) and 80 GHz versions, and antennas for each model are designed to meet application-specific installations. Liquid level measurement devices include OPTIWAVE 5400 (24 GHz) for liquids in basic process applications; 7400 (24 GHz) for agitated and corrosive liquids; 7500 (80 GHz) for liquids in narrow tanks with internal obstructions and 3500 (80 GHz) for liquids with hygienic requirements. These replace the 7300. Solids level measurement devices include OPTIWAVE 6400 (24 GHz) for solids ranging from granulates to rocks and 6500 (80 GHz) for powders and dusty atmospheres. These replace the OPTIWAVE 6300. Current OPTIWAVE 6300 and 7300 devices will be phased out at the end of 2017. Spare parts will be available during 2018 and later.
