|1921||Ludwig KROHNE starts manufacturing variable area flowmeters in Duisburg, Germany, to measure the flow of air, gases and liquids.|
|1952||The first electromagnetic flowmeter for industrial
measurement is launched.
|1955||Production of mechanical level meters for measuring
liquids in tanks and containers begins.
|1966||Construction of the world's largest calibration
rig in Sliedrecht/Netherlands
|1974||INOR, KROHNE subsidiary from Sweden, presents
world's first headmounted transmitter.
|1989||KROHNE introduces the first FMCW radar level meter for process tanks, pioneering the use of radar level measurement technology in process applications.|
|1994||First straight tube Coriolis mass flowmeter.|
|1995||KROHNE launches the first TDR guided radar meter. It is able to reliably determine the level of liquids and solids as well as liquid interface.|
