Krohne ( spelling: KROHNE) is one of the leading international providers of process measurement technology . The Duisburg- based company employed over 4,000 people worldwide in 2019 and achieved sales of EUR 595.4 million.

history

The company was founded in 1921 by Ludwig Krohne. This began with the manufacture of variable area flowmeters . In 1936 the company was able to move from rented premises to its own buildings, which were destroyed in the Second World War. Since both Ludwig Krohne and his son Karl died, Ludwig's wife Anna ran the company in the post-war years. In 1949 she asked her grandson Kristian Rademacher-Dubbick to join the company. Under his leadership the rise to one of the leading companies for process measurement technology began. Currently managed by Attila Bilgic, Ansgar Hoffmann, Stephan Neuburger, Ingo Wald, the company is developing into a provider of measurement solutions such as B. Measurement systems and additional services that support modern process control concepts. The company remains independently owned by the Rademacher-Dubbick family.

Products

Krohne is active in numerous industries and offers its own products, solutions and services for this purpose. B. distinguished by industry-specific approvals, materials, process connections or designs. The most important are chemicals and petrochemicals, food and beverages, water and wastewater, oil and gas, power generation and distribution, shipping, papermaking, pharmaceuticals, and minerals and mining.

The current portfolio includes process measurement technology, measurement technology solutions and services: In process measurement technology, Krohne is a full-range supplier with the product areas of flow, level, temperature, pressure and analysis measurement technology, each of which spans different measurement principles. The metrological solutions include complete measurement systems, skids and system modules e.g. B. for the (legal for trade) measurement of liquids and gases, as well as software systems z. B. for pipeline leak monitoring and location, hydrocarbon management or tank management on ocean-going tankers. The Services area includes services such as consulting, project management and engineering as well as maintenance concepts for individual measuring points or the instrumentation of a complete system. The calibration of measuring devices and calibration services represent a special competence of the company, which operates over 140 calibration facilities worldwide.

Krohne conducts research and development activities (approx. 10% of the employees work in this area) and has presented some innovations that have influenced the design and management of industrial processes today or have made it possible in the first place. These include B.

• 1952: Magnetic-inductive flow meter (MID) for industrial use
• 1959: Level indicator with float and magnetic coupling
• 1978: 2-path ultrasonic flow meters
• 1989: Radar level measuring device for process applications with FMCW technology
• 1994: Coriolis mass flowmeter with straight measuring tube
• 1996: Magnetic-inductive flow meter for partially filled pipes
• 2000: 2-wire TDR level measuring device
• 2006: 2- wire vortex flow meter with integrated pressure and temperature compensation
• 2008: 12-beam ultrasonic flow meter for custody transfer with compensation and diagnostic functions
• 2010: EMF with rectangular cross-section for installation without inlet and outlet sections
• 2013: Coriolis mass flowmeter with immunity to air or gas inclusions in the medium
• 2015: Multi-phase flow meter based on magnetic resonance technology
• 2017: Radar level measuring devices with 80 GHz operating frequency.
• 2019: Process node that combines sensors, actuators and control in one module and uses AI (Joint Venture Focus-on , see below).

Branches

The company operates 16 production facilities in 11 countries and a total of 50 own or joint venture branches. There are exclusive agencies at 55 other locations.

The individual production facilities specialize in certain product groups. In addition to production, the measurement devices are also calibrated at several locations . In Duisburg, over 700 employees develop and manufacture all the electronic components used in the measuring devices, and the development and production of the variable area measuring devices and vortex flowmeters also takes place here. In Minden, Krohne manufactures pressure gauges for flow measurement using differential pressure, process pressure measurement and level measurement using hydrostatic pressure.

Further plants are located in (country, date of foundation, main products are indicated in brackets)

• Malmö (Sweden, 1940, temperature sensors and transmitters),
• Brevik (Norway, 1957, development of marine technology).
• Romans-sur-Isère (France, 1960, level meters and switches, flow control devices),
• Dordrecht (Netherlands, 1962, Ultrasonic, Electromagnetic, and Magnetic Resonance Flowmeters),
• Wellingborough (UK, 1976, Coriolis mass flow meters),
• Pune (India, 1984, vortex flowmeters),
• Samara (Russia, 1994, level meters, ultrasonic flow meters),
• Embu (Brazil, 1994, magnetic-inductive flowmeters for the entire American market),
• Shanghai (China, 2004, 76MA, Magnetic Inductive Flow Meters, Coriolis Mass Flow Meters, Level Meters).

In addition, two further joint ventures are operated in China, one in Shanghai (founded in 1987) and one in Chengde (founded in 1991). The location in the USA in Beverly, Massachusetts was expanded to a local production and manufacturing facility and opened in September 2018.

The Focus-on joint venture with Samson AG was founded in September 2019 ; the seat is Dordrecht. Focus-on is to develop, manufacture and market autonomous actuators for the process industry 4.0.
