Abstract
An electromagnetic flow meter includes a flowtube including a coil disposed in the vicinity of a measurement tube, and electrodes disposed on the measurement tube, a converter including an excitation unit configured to generate an excitation signal and output the excitation signal to the coil through an excitation cable, and a detection signal receiving unit configured to receive a detection signal from the electrodes through a signal cable, and generate a flow rate signal, and a miswiring detection unit configured to perform miswiring diagnosis on the excitation cable or the signal cable on the basis of a difference between a change amount of the flow rate signal when the excitation signal is being output and a change amount of the flow rate signal when the excitation signal is not being output.
