Explain the advantages and limitations of electromagnetic flowmeters in detail

Abstract: The advantages and limitations of electromagnetic flowmeters are detailed information provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The measurement channel of the electromagnetic flowmeter is a smooth straight pipe with no obstruction flow detection piece, which is suitable for measuring liquid-solid two-phase fluids containing solid particles, such as pulp, coal-water slurry, mineral pulp, mud and sewage, etc., because it is not easy to block. Electromagnetic flowmeters do not generate flow due to detection. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is an article detailing the advantages and limitations of electromagnetic flowmeters. The measurement channel of the electromagnetic flowmeter is a smooth straight pipe with no obstruction flow detection piece, which is suitable for measuring liquid-solid two-phase fluids containing solid particles, such as pulp, coal-water slurry, mineral pulp, mud and sewage, etc., because it is not easy to block. The electromagnetic flowmeter does not produce pressure loss caused by the detected flow, and the resistance of the meter is only the resistance along the pipeline of the same length, and the energy saving effect is remarkable. It is most suitable for large-diameter water supply pipelines that require low resistance loss. The volume flow measured by an electromagnetic flowmeter is actually not significantly affected by slow changes in fluid density, viscosity, temperature, pressure and conductivity. Compared with most other flow meters, the electromagnetic flowmeter has lower requirements for the straight pipe section in front. The electromagnetic flowmeter has a large measuring range, usually 20: 1 ~ 50: l, and the optional flow range is wide. The liquid flow velocity of the full scale value can be selected within 0.5 ~ 10m/s. Some types of meters can expand and reduce the flow according to the need in the field (for example, there is a 4-digit potentiometer to set the constant of the meter), and it is not necessary to remove it for offline real flow calibration. The caliber range of electromagnetic flowmeters is wider than other varieties of flowmeters, from a few millimeters to 3m. It can measure forward and reverse bidirectional flow, and also measure pulsating flow, as long as the pulsation frequency is much lower than the excitation frequency. The meter output is linear in nature. It is easy to select the material variety of the parts in contact with the fluid, which can be applied to corrosive fluids. Disadvantages Electromagnetic flowmeters cannot measure liquids with very low conductivity, such as petroleum products and organic solvents. Electromagnetic flowmeters cannot measure gases, vapors and liquids that contain many larger bubbles. General-purpose electromagnetic flowmeters cannot be used for higher temperature liquids due to the limitations of lining materials and electrical insulation materials; some models of meters are used for liquids below room temperature, and the insulation is damaged due to condensation (or frost) outside the measuring tube. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
