Abstract
An excitation circuit, which is used in an electromagnetic flow meter, measures a flow rate value for a fluid, based on an electromotive force. An excitation coil, which is provided on an outside of a measurement tube, is supplied with an excitation current, where, in response, the electromotive force, which is perpendicular to a magnetic field of the excitation coil that is generated in the fluid within the measurement tube, is detected by a pair of electrodes provided on the measurement tube.
