Abstract
One embodiment of an electromagnetic flow rate measurement system includes electromagnetic flowmeters arranged at intervals from one another in the peripheral direction of an annular flow passagein which an electric conductive fluid flows. Each of the electromagnetic flowmeters comprises: an excitation member that has magnets arranged at intervals from one another in the outer peripheral surface of the annular flow passage so as to form a magnetic field in the direction perpendicular to the outer peripheral surface of the annular flow passage; and electrodes that are provided between the magnets of the excitation member and between the magnets of the excitation member so as to measure voltage generated when the electric conductive fluid crosses the magnetic field. The polarities of the magnets at the end portions of the closest excitation members of the adjacent electromagnetic flowmeters are opposed to each other.
