In May 2008, Endress+Hauser , manufacturers of electromagnetic flowmeters, called as magmeters, saw sales of their magmeters reach the one million mark since production commenced 31 years ago.
With water management being one of the main areas of use for the flowmeters, Endress+Hauser is celebrating the occasion by donating to an important community water project in Southern Africa.
The main aim of this humanitarian project is to ensure long-term provision of 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 their 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.
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 harsh environmental conditions including challenging mining applications. Due to improved manufacturing techniques and major advances in the electronic filtering of the measured signals, magmeters 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 such as water, wastewater, sludges, pulps, pastes, acids, alkalis, juices, fruit mashes can be measured with magmeters.
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 magmeters used worldwide to measure conductive liquids are based on Father Bonaventura Thurlemann’s research.
