What is the purpose of an electromagnetic flow meter?

　　Electromagnetic flowmeter is designed and manufactured according to Faraday's principle of electromagnetic induction. Electromagnetic flowmeter by setting up a pair of magnetic poles in the liquid pipeline, when the liquid flows through the magnetic poles, the conductivity in the liquid will lead to changes in the magnetic field, thus inducing an electric potential signal in the liquid. By sensing this signal, the electromagnetic flowmeter can measure the flow rate of the liquid.

　　Electromagnetic flowmeter has many advantages. Firstly, it has high accuracy and can achieve high precision and repeatability of flow measurement. Secondly, the electromagnetic flowmeter has a wide range of applications and can be applied to a variety of fluids, including liquids, steam and so on. In addition, because the electromagnetic flowmeter will not be affected by the composition of the medium, it only needs to set the basic parameters in the setting process of the instrument, and then it is able to carry out the measurement directly. In addition, the measurement process of the electromagnetic flowmeter will not interfere with the measured substance, and will not cause any pollution or damage to the measured substance.

　　Electromagnetic flowmeters have a wide range of uses. Generally speaking, they are widely used in the fields of chemical industry, mining industry, water supply and drainage, pharmacy, food, paper making and so on. In the field of chemical industry, electromagnetic flowmeter is usually used to measure the flow rate of various liquids, such as various solutions, acids, alkalis and so on. In the field of mining, electromagnetic flowmeter can be used to measure the flow of mineral water and various water treatment process flow control. In the field of water supply and drainage, electromagnetic flowmeter is usually used to measure the flow of demineralised water and various wastewater. In the pharmaceutical field, electromagnetic flowmeter can be used to measure the flow of all kinds of liquid. In the field of food manufacturing, electromagnetic flowmeter can be used to measure the flow of liquid ingredients, mixture, etc.. In the field of papermaking, electromagnetic flowmeter can be used to measure the flow of various kinds of pulp.

　　In short, the electromagnetic flowmeter is a very useful flow measurement instrument, which has a wide range of applications, can achieve high-precision measurement, applicable to a variety of liquids, will not produce any pollution and damage to the measured material, has a high application value.
