In May 2008, Endress+Hauser, the world’s leading producer of electromagnetic flowmeters (magmeters), saw sales of their flowmeters top the one million mark since production commenced 31 years ago.
Through innovative products, considerable investment in research and development, as well as future-oriented services, the independent family-run company has been able to gain the trust of its customers and continually increase sales. As a result, 500,000 electromagnetic flowmeters have been sold in the past seven years alone.
Endress+Hauser Flowtec AG headquartered in Reinach, Switzerland, is one of the world’s biggest providers of a variety of industrial flowmeters for liquid, gas and steam. With water management being one of the main areas of use for the flowmeters, Endress+Hauser is celebrating the landmark occasion by donating to an important community water project in Southern Africa.
The main aim of this humanitarian project is to ensure the long-term provision of the drinking water supply and sanitation in an area with about 300,000 inhabitants. Working together with villagers and the authorities, disintegrated wells are being rebuilt, silted-up boreholes cleared and faulty pumps replaced.
Endress+Hauser became involved in flow measurement during the 1960s. However, the real breakthrough came in the mid 1970s when the company geared its business strategy towards environmental technology and entered the water and wastewater market.
In 1991, the flow market continued to witness growth in all industries creating a need for Endress+Hauser to expand its production facilities through a new production plant in Cernay, France. Over the last fifteen years, and with the use of hi-tech manufacturing systems, Flowtec Cernay has developed into the biggest magmeter production facility in the world, with the biggest calibration laboratory and highest accuracy available.
Magmeters are found in almost all industries, which need to measure the flowrates of conductive liquids, but are primarily used in water/wastewater, mining and the food industry. The robust construction permits their use under the harshest environmental conditions including challenging mining applications. Due to improved manufacturing techniques and major advances in the electronic filtering of the measured signals, mag flowmeters have continuously dropped in price and increased in accuracy.
Typical measuring tasks include recording and monitoring continual flow rates, filling and dosing applications, as well as custody transfer. A large number of aqueous-based fluids can be measured with electromagnetic flowmeters: water, wastewater, sludges, pulps, pastes, acids, alkalis, juices, fruit mashes and more.
Father Bonaventura Thurlemann (1909 – 1997)
The mastermind behind the first magmeter was Swiss inventor and Benedictine priest, Father Bonaventura Thurlemann. His 1941 publication “Method of Electrical Velocity Measurement in Liquids” prepared the way for the practical application of Faraday’s Laws to volume flow measurement of liquids.
The hundreds of thousands of magnetic flowmeters used worldwide to measure conductive liquids are based on Father Bonaventura’s research.
Father Bonaventura never made profit from his invention because he never patented it. In a 1984 speech at the opening of the magmeter production facility at E+H’s Flowtec AG (Reinach, Switzerland), Father Bonaventura said the patenting process was too complicated for him.
He was 84 years old when he died May 30 1997.
