An electromagnetic flowmeter includes a exciting coil, exciting section, and arithmetic processing section. The exciting coil applies a magnetic field to a fluid flowing in a pipe line. The exciting section supplies an exciting current to the coil. The arithmetic processing section calculates a measurement flow rate on the basis of the measurement signal detected from the excited fluid. The arithmetic processing section includes a measurement flow rate calculation section. In calculating a measurement flow rate from the measurement signal, the measurement flow rate calculation section corrects the flow rate calculated from the measurement signal on the basis of one of adjustment coefficients, set in advance in correspondence with current values of exciting currents, which corresponds to a current value of an exciting current by which the measurement signal is obtained.
