Intelligent electromagnetic flowmeters have the advantages of rectangular wave magnetic fields and overcome the disadvantages of sinusoidal wave magnetic fields. They can also reduce errors caused by power supply voltage fluctuations, power supply frequency changes, and excitation coil impedance changes. They also have good zero point stability and are not affected by fluid noise interference.
The measurement principle of an electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The sensor primarily consists of a measuring tube with an insulating lining, a pair of electrodes installed through the tube wall, a pair of coils, and an iron core that generates an operating magnetic field.
Electromagnetic flowmeters can be used to measure the volume flow of conductive liquids in closed pipes. They are widely used for flow measurement and control in the chemical and petroleum industries, metallurgy, water supply and drainage, agricultural irrigation, papermaking, food and beverage, and pharmaceutical industries.
Product features
