是一种体积流量测量仪表，在测量过程中，它不受被测介的温度、粘度、密度以及导率（在一定范围）的影响。 1. The electromagnetic flowmeter is a volume flow measuring 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 it has been calibrated with water.
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 or turbulent) in a symmetrical distribution. Therefore, the range of the electromagnetic flowmeter is extremely wide, the measurement range can reach 100: 1, and some even reach the operational flow range of 1000: 1.
的传染器结构简单，测量关内没有可移动部件，也没有任何阻碍流体流动的节流部件。 3. The structure of the infector of the electromagnetic flowmeter is simple, there are no moving parts in the measurement gate, and there are no throttling parts that hinder fluid flow. Therefore, it will not cause any additional pressure loss when the fluid passes through the flow meter, and it is one of the flow meters with the lowest energy consumption in the flow meter.
4. The electromagnetic flowmeter has no mechanical inertia and is sensitive in response. It can measure the instantaneous pulsating flow, and it can also measure the flow in both directions.
的应用和发展奠定了基础。 5. The caliber range of industrial electromagnetic flowmeters is extremely wide, from a few millimeters to machine meters , and there are already experimental validation equipment with a mouth diameter of 3M in China, which has laid the foundation for the application and development of electromagnetic flowmeters .
