What is the difference between electromagnetic flowmeter and vortex flowmeter?

For those who often use and purchase flow meters, vortex flow meters and electromagnetic flow meters are very common flow measurement instruments. They are not only similar in appearance, but also in function. They are also similar, so although many people have used them for a long time, they still can't distinguish the differences between the two. Today we will give you some popular science.

Vortex flowmeter measures the size of the vortex generated by the fluid passing through the cylinder in the device, and compares the flow rate with the vortex The frequency of the electromagnetic flowmeter is used to calculate the flow rate. There is a component called a conductive fluid in the electromagnetic flowmeter, which cuts the magnetic lines generated during measurement. Therefore, it can only measure pure water, and its measurement range is not as good as that of the vortex street. flow meter.

The working principles of the two are also different. The vortex flowmeter obtains the flow value by measuring the frequency of the vortex, while the electromagnetic flowmeter relies on the principle of Faraday's electromagnetic effect. Measurement of fluids. The media that can be measured are also different. In addition to liquids, vortex flowmeters can measure steam, compressed air and other gases, while electromagnetic flowmeters can only measure liquids.

The temperature requirements of the medium are also different. The electromagnetic flowmeter requires that the temperature of the measuring medium cannot be too high. , and the vortex flowmeter does not have such strict temperature requirements, and high-temperature gases or liquids can also be easily measured.

Although there are many differences between vortex flowmeters and electromagnetic flowmeters in terms of measurement medium range, functionality, etc., both are new flow measurement instruments and there is no difference between them. They have stable performance, accurate measurement, and low failure rate. When choosing, you can choose the type that suits you based on your own working conditions and usage needs.
