LUDWIG KROHNE & SOHN founded. Production of variable-area flowmeters. First electromagnetic flowmeter for industrial applications (TOBI 1952 / KROHNE Altometer 1962) Precision forming of cylindrical glass tubes into high accuracy tapered measuring tubes First inductive transducers for variable area flowmeters in Germany Level indicator with float and magnetic coupling Introduction of an accurate conversion method for variable area flowmeters, subsequently adopted as VDI Code First electromagnetic flowmeter as a product of the KROHNE Group (ALTOMETER) Construction of the worldâ&#x20AC;&#x2122;s largest calibration rig in Sliedrecht/Netherlands Development of the pulsed DC field for electromagnetic flowmeters Development of double-beam ultrasonic flowmeters Construction of a still bigger and more accurat calibration rig in Sliedrecht/NL First delivery of an ultrasonic flowmeter to Shell for crude oil measurements Development and production of the Coriolis mass flowmeter First microwave radar (FMCW) level gauge for level measurement First straight-tube Coriolis mass flowmeter First electromagnetic flowmeter for partially filled pipes (TIDALFLUX). ALTOSONIC V is the first ultrasonic liquid custody transfer meter in the world. Commissioning of an eleventh calibration rig, the largest and most accurate in the world, at KROHNE Altometer, 43 metres high calibration tower, calibration volume uncertainty < 0.013% First electromagnetic 2-wire flowmeter with full process application compatibility, intelligent power optimization, high dynamic The new generation of massflow meters with straight tube, OPTIMASS. First 3-beam ultrasonic flowmeter for the chemical industry, UFM 3030. New Generation electromagnetic flowmeters OPTIFLUX with built-in diagnostics for process, accuracy and meter integrity. The new generation Level Radar OPTIWAVE and guided Radar OPTIFLEX with unique wizard-driven operating concept Most efficient clamp-on ultrasonic flowmeter OPTISONIC 6300 OPTISWIRL 4070 C first vortex flowmeter with integrated pressure and temperature compensation in 2-wire technology ALTOSONIC V12 combines, for the first time in an ultrasonic flowmeter, the advantages of the parallel chord concept and the reflection technique, setting a new standard in ultrasonic custody transfer gas metering.
