What is the law of electromagnetic induction based on the electromagnetic flow meter?

Abstract: The information on what electromagnetic flow meter is based on the law of electromagnetic induction is provided by excellent flowmeter and flowmeter manufacturers. The electromagnetic flowmeter works based on Faraday's law of electromagnetic induction and consists of a sensor and a converter. The sensor is mainly composed of a measuring tube lined with insulating materials, a pair of electrodes installed through the wall of the measuring tube, and a working magnetic field. Align. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of the electromagnetic induction law based on which electromagnetic flowmeters work. The electromagnetic flowmeter works based on Faraday's law of electromagnetic induction and consists of a sensor and a converter. The sensor is mainly composed of a measuring tube lined with insulating materials, a pair of electrodes installed through the wall of the measuring tube, and a working magnetic field. Composed of coil and iron core. When the conductive medium flows through the sensor measuring tube, there is a stable magnetic field with a magnetic induction intensity generated by the transmitter in an interval perpendicular to the flow direction of the medium, and the conductive fluid with an average flow rate of sports. Therefore, an induced potential is generated on the two detection electrodes that are parallel to the cross section of the pipeline and perpendicular to the direction of the magnetic field line. According to the law of electromagnetic induction: the instrument constant, when the diameter D of the pipeline has been determined and the magnetic induction intensity is kept constant, is a constant. At this time, the induced potential has a linear relationship with the volume flow, that is, the induced potential E is measured, and the volume flow q of the medium is also measured. There are no throttling and moving parts in the measuring conduit, so the pressure loss is very small, saving energy, and can measure the flow of fluids containing particles, suspended solids, etc. ②As long as the lining and the electrode are in contact with the medium, the purpose of anti-corrosion can be achieved only by selecting the materials of the two; as long as the electrode is not polluted, the accuracy of the instrument will not be reduced for a long time. ③There is a linear relationship between the output current of the electromagnetic flowmeter and the flow rate. And it is not affected by the physical properties of the liquid; therefore, it can be used to measure the flow rate of other conductive liquids or solid-liquid two-phase media without correction after only calibrating with water. ④SMART converter adopts novel excitation method, low power consumption, stable zero point, high precision, flow range up to 100:1, convenient parameter setting, reliable programming, and self-test and self-diagnosis functions. ⑤ No mechanical inertia, flexible response, can measure pulsating flow. According to the characteristics of the measured medium and the advantages of the electromagnetic flowmeter, it can be seen that the electromagnetic flowmeter is very suitable for the measurement of chlor-alkali. Although the price of electromagnetic flowmeter is more expensive, it has high precision, low maintenance, long service life and high cost performance. Differential pressure flowmeters, turbine flowmeters, oval gear flowmeters, etc. are all affected by the working state of the fluid and parameters such as fluid density and viscosity, which increase the measurement error. Due to the wear of the measuring element by the solid particles, the service life is reduced, and even the blockage cannot be used, and the corrosion can not be solved. Our factory used an oval gear flowmeter to measure the diaphragm electrolyte, but it was stopped due to the blockage of salt precipitation in the electrolyte, and finally replaced with an electromagnetic flowmeter. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
