6 Advantages of electromagnetic flowmeters

　　1. The electromagnetic flowmeter has a simple sensor structure, and there are no moving parts in the measuring tube, nor any throttling parts that hinder the flow of fluid. Therefore, when the fluid passes through the flowmeter, it will not cause any additional pressure loss, and it is one of the flowmeters with the lowest operating energy consumption.

　　2. It can measure the flow of dirty media, corrosive media and suspended liquid-solid two-phase flow. This is because there is no obstruction to the flow inside the measuring tube of the instrument. Only the measuring tube lining and electrodes are in contact with the measured fluid. The materials can be selected according to the properties of the measured fluid. For example, using polytrifluoroethylene or polytetrafluoroethylene as the lining can measure various corrosive media such as acids, alkalis, and salts; using wear-resistant rubber as the lining is particularly suitable for measuring liquid-solid two-phase flows such as ore slurry and cement slurry with solid particles and large wear, as well as various suspended liquids such as fiber-containing liquids and pulp.

　　3. Electromagnetic flowmeter is a volume flow measurement instrument. During the measurement process, it is not affected by the temperature, viscosity, density and conductivity (within a certain range) of the measured medium. Therefore, the electromagnetic flowmeter only needs to be calibrated with water and can be used to measure the flow of other conductive liquids.

　　4. The output of the electromagnetic flowmeter is only proportional to the average flow velocity of the measured medium, and has nothing to do with the flow state (laminar flow or turbulent flow) under symmetrical distribution. Therefore, the range of the electromagnetic flowmeter is extremely wide, and its measurement range can reach 100:1, and some even reach 1000:1.

　　5. The electromagnetic flowmeter has no mechanical inertia and is sensitive to reaction. It can measure instantaneous pulsating flow as well as flow in both positive and negative directions.

　　6. The caliber range of industrial electromagnetic flowmeters is extremely wide, ranging from a few millimeters to several meters, and there are actual flow calibration equipment with a caliber of up to 3 meters in China, which has laid the foundation for the application and development of electromagnetic flowmeters.
