1. No mechanical inertia, sensitive response, can measure instantaneous pulsating flow, and can also measure flow in both forward and reverse directions.
2. 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 measuring range of electromagnetic flowmeter is extremely wide, and its measuring range can reach 100:1, and some even reach the operational flow range of 1000:1.
3. The sensor structure of the electromagnetic flowmeter is simple. There are no movable parts in the measuring tube, and there are no throttling parts that hinder the flow of fluid. Therefore, when the fluid passes through the flow meter, it will not cause any additional pressure loss, and it is one of the flow meters with the lowest operating energy consumption among flow meters.
4. The diameter range of industrial electromagnetic flowmeters is extremely wide, from a few millimeters to several meters, and there are real-flow calibration equipment with a diameter of 3m in China, laying the foundation for the application and development of electromagnetic flowmeters.
5. The 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 can be used to measure the flow of other conductive liquids only after being calibrated with water.
6. It can measure the flow rate of dirty media, corrosive media and suspended liquid-solid two-phase flow. This is because there are no flow-impeding parts inside the measuring tube of the instrument, and only the lining and electrodes of the measuring tube are in contact with the measured fluid, and their materials can be selected according to the properties of the measured fluid.
