Electromagnetic flow meter measuring principle

Abstract: The information on the measurement principle of electromagnetic flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Electromagnetic flowmeters are suitable for measuring the volume flow of conductive liquids and slurries in closed pipes, such as clean water, sewage, various acid-base solutions, mud, pulp, pulp and food liquids. The measurement principle of electromagnetic flowmeters is based on Faraday electromagnetism. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on the measurement principle of electromagnetic flowmeters. Electromagnetic flowmeters are suitable for measuring the volume flow of conductive liquids and slurries in closed pipes, such as clean water, sewage, various acid-base solutions, mud, pulp, pulp and food liquids. The measurement principle of the electromagnetic flowmeter is based on Faraday's law of electromagnetic induction: when the conductive liquid moves in the magnetic field to cut the magnetic field line, an induced potential is generated in the conductor, and the induced potential is E: E=KBVD where: K-----meter Constant B-----magnetic induction intensity V-----measuring the average flow velocity in the pipe section D-----measuring the inner diameter of the pipe section When measuring the flow rate, the conductive liquid flows at a speed V through the flow direction perpendicular to the flow direction. Magnetic field, the flow of conductive liquid induces a voltage proportional to the average flow rate, the induced voltage signal is detected by two or more electrodes in direct contact with the liquid, and sent to the converter through the cable for intelligent processing, Then LCD display or convert to standard signal 4-20mA and 0-5kHz output. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Measurement Principle of Electromagnetic Flow Meter'
