To generate a magnetic field, excitation coils are installed around the measuring tube. The generated magnetic field passes through the fluid, thereby generating an induced electromotive force in the fluid. Electrodes are installed at the positive and negative positions of the induced electromotive force to measure the magnitude of the induced electromotive force.
