The electromagnetic flowmeter is a meter for measuring the volume flow of the conductive medium. It is mainly composed of electromagnetic flow sensors, flow conversion and processing instruments. With throttling flow blocking parts, not easy to block, good corrosion resistance, a wide range of applicable media, measurement accuracy is not affected by the measured medium temperature, viscosity, density, pressure, specific gravity and other physical parameters, its value in a certain conductance The rate range is independent of the type of liquid being calibrated. In addition to measuring the flow of general liquids, electromagnetic flowmeters can also measure the volumetric flow rates of liquid-solid two-phase liquids, high-viscosity liquids, and salts, strong acids, and strong alkalis, and can be widely used in cement, chemical, textile, metallurgy, Mine, papermaking, medicine, water supply and drainage, food and beverage, sugar, brewing and other industrial technology departments, especially in the field of environmental protection. At present, the electromagnetic flowmeter has become an effective tool for the environmental protection department to quantitatively manage the company's sewage discharge.
After decades of development, domestic and foreign manufacturers of electromagnetic flowmeters have mushroomed rapidly. At present, there are more than 50 professional magnetic flowmeter production plants abroad, of which there are at least 18 in the United States, at least 10 in Germany and Japan, and at least 5 in the United Kingdom. The professional manufacturer of electromagnetic flowmeters that are competitive and have a certain scale of production are: Bailey. Fischer & Porter, Krohne, Yokogawa, Endress+Hauser, ABB KentTayler, Foxboro, Samurai, Brook/Rosemount, Danfoss, Toshiba, Fuji Electric, Turbobork, Sparling, etc.
The application of electromagnetic flowmeters in China began in the early 60s. Shanghai Guanghua Instrument Factory was the first company to produce this product in China. At present, the domestic instrument industry has been able to provide a more complete series of instruments, in which Shanghai Guanghua Aimei Meite Instrument Co., Ltd. can achieve a maximum diameter of 3m flowmeter. In recent years, the number of domestic sales of magnetic flowmeters in China is estimated to be between 8500.10000 units, and will increase by 35% annually. To date, there are at least 21 electromagnetic flowmeter manufacturing plants in China, and the output is ranked in the top four: Shanghai Guanghua Aimei Meite Instrument Co., Ltd., Kaifeng Instrument Factory, Shanghai Yokogawa Electric Co., Ltd., and Shanghai Guanghua Instrument Factory. They occupy about 80% of the electromagnetic flow meter market in China. In the current ten major flow meter types (differential pressure type, float type, volumetric type, electromagnetic type, turbine type, vortex type, ultrasonic type, Coriolis mass type, thermal type, and open channel type), electromagnetic flowmeters The sales amount and the number of production units all occupy a considerable proportion. According to statistics, the electromagnetic flowmeter's market share in the world's flowmeter in 1997 ranked second only to the differential pressure flowmeter. The Kaifeng electromagnetic flowmeter currently ranks second in market share, and its market growth rate is greater than the pressure difference flowmeter. We can expect that in the next few decades, with the increase in the advantages of smart electromagnetic flowmeters and the continuous resolution of shortcomings, electromagnetic flowmeters will exceed the pressure-difference flowmeters in the market share according to their unique advantages. Flowmeter market leader.
