The electromagnetic flowmeter has a wide range of applications. With the breakthrough development of research and development technology in recent years, the application of low-frequency rectangular wave, dual-frequency rectangular wave excitation technology and microprocessor technology in product research and development has brought the measurement unit of electromagnetic flowmeter.
The performance of the electromagnetic flowmeter and the data processing unit, whether it is the anti-interference ability of the electromagnetic flowmeter or its measurement accuracy, has been greatly improved, making the vitality of the electromagnetic flowmeter more exuberant. At present, it can be seen in most of the domestic heavy industry and light industry production enterprises. Its figure, the electromagnetic flowmeter is made according to Faraday's law of electromagnetic induction. It is used to measure the volume flow of conductive liquids with conductivity greater than 5μs/cm. It is especially suitable for a variety of highly corrosive media and difficult to measure solid-liquid two-phase places with high requirements, such as industrial sewage, paper pulp, mud, and mineral pulp. With the advent of non-full-tube electromagnetic flowmeters and electrodeless flowmeters (used for low-conductivity liquids that can still work when the lining has an insulating layer), the application fields of electromagnetic flowmeters have been further expanded.
