Abstract
An electromagnetic flowmeter of this invention includes a measurement tube for passing a fluid to be measured, alternating magnetic field application means for applying alternating magnetic field and periodically switching magnetic fields applied in a first direction on a plane perpendicular to a direction in which the fluid flows and in a second direction opposite to the first direction, sampling means for sampling electromotive force caused in the fluid by the magnetic fields in the first and second directions by plural times in the same direction in one period, and arithmetic means for deriving the flow rate by the arithmetic process by excluding a sampling value which is contained in the sampling values obtained by the plurality of sampling operations and which exceeds a preset range or replacing the same by a simulated value.
