About KROHNE
KROHNE Messtechnik GmbH, headquartered in Duisburg, is a manufacturer of process instrumentation, in particular flowmeters based on Coriolis, electromagnetic and ultrasonic measuring principles as well as variable area flowmeters, complemented by radar level measurement, signal converters and flow computers. The product portfolio covers measuring devices from the smallest nominal diameters (from DN2.5 or DN15) up to large pipe applications up to DN3000 as well as custody transfer metering systems for gases such as natural gas and hydrogen (ALTOSONIC V12, up to DN1600 and PN450). Materials for measuring tubes and components include stainless steel, carbon steel, Hastelloy, PTFE/PFA/ETFE, rubber and ceramic. The company serves industries such as chemicals, oil & gas/pipelines, food & beverage, water/wastewater, data centers, hydrogen, life sciences, marine, mining and power generation. In addition to manufacturing, KROHNE offers a service portfolio including calibration (over 150 calibration rigs, accredited to ISO 17025), commissioning, on-site verification, maintenance and engineering of metering systems.
