Analysis of electromagnetic flowmeter-related issues with respect to ultrasonic flowmeters The electromagnetic flowmeter works according to the principle of Faraday's electromagnetic induction law. When a conductor with conductive properties is used to cut magnetic force lines in a magnetic field, an induced electromotive force is generated on the upper and lower sides thereof, and the direction is in accordance with the right-hand rule. Therefore, the application of general electromagnetic flowmeter has certain requirements for the conductivity of the fluid. The application process takes 5us/cm as the boundary. Electromagnetic flowmeters and ultrasonic flowmeters are velocity flowmeters, all of which are influenced by factors such as: fluid flocculation (fluid is evenly distributed), lining internal scale. The error caused by the flocculation of the fluid: When the flow velocity of the liquid in the pipeline is axisymmetrically distributed, and in a uniform magnetic field, the magnitude of the electromotive force generated on the flowmeter electrode is independent of the flow velocity distribution of the fluid and is proportional to the average flow velocity of the fluid. , Otherwise, the induced electromotive force generated by the electrodes is different. Therefore, it is necessary to select electromagnetic flowmeters for measuring pipe sections with small fluid flow turbulence to avoid unnecessary errors. Errors caused by lining internal scales: In chemical companies, water treatment companies, and meters that measure water for daily use, we often see a layer of scale or chemical contamination on the inner wall. Do not underestimate this thin layer. It can Change the electromotive force deviation of the electromagnetic flowmeter and thus generate a zero misalignment. So we often see some sewage treatment plants, in order to improve its measurement accuracy, often cleaning the electrodes inserted into the electromagnetic flowmeter. At present, electromagnetic flowmeters still dominate the market in fluid metering, energy-saving detection, and other industries. With the increase in electronic chip technology and computer computing efficiency, there has been a trend to replace them with ultrasonic flowmeters.
