Magnetic Flowmeter Applications
2019-06-14
Although there are numerous types of magnetic flowmeters available for measuring liquid flow rates, all of them function according to the fundamental principles of Faraday’s law, which dictates the relationship between a moving conductor and the voltage it creates within a magnetic field. But despite their similarities, some magnetic flowmeters are better suited to specific tasks than others, making flowmeter selection and proper application important concerns in a fluid measurement project. Issues of cost, accuracy, reliability, and ease of use are some of the significant factors involved in choosing a flowmeter.
In terms of application, the metallurgical properties of the fluid conduit and the measuring apparatus can greatly influence measurement effectiveness. In addition, a fluid’s velocity profile and the flowmeter system’s capacity for handling flow disturbances or other interference often determine the type of device that would be most appropriate for a given application. In order to ensure reliable performance over an expected period of operation and volume of moving fluid, flowmeter scale—both in size and velocity limits—should be taken into careful account.
