Abstract
The electromagnetic flowmeter utilises the same basic principle as the electrical generator: when a conductor moves across a magnetic field a voltage is induced in the conductor, and the magnitude of the voltage is directly proportional to the speed of the moving conductor. If the conductor is a section of conductive liquid flowing in a non-conductive pipe through a magnetic field, and electrodes are mounted in the pipe wall at the positions shown in Figure 6.1, the voltage induced across the electrodes should be proportional to flowrate.
It’s clever, but is it art?
