流量計。Excitation means for applying a binary or ternary steady magnetic field to the fluid;
The above-mentioned excitation has an amplifier that amplifies the voltage proportional to the flow velocity of the fluid generated between the pair of electrodes by the magnetic field, and a current control circuit that controls the current flowing through the two reciprocating transmission lines according to the output of this amplifier. In an electromagnetic flowmeter in which all circuits such as means, amplifiers, and current control circuits are operated by current supplied from the two transmission lines, the number of turns of the excitation coil is increased to adjust the steady value of the excitation current to a two-wire system. base electromagnetic 2
A two-wire type electromagnetic flow rate system characterized in that the number of turns of the excitation coil is determined so that the excitation switching time including the non-excitation period is approximately 1/2 or less of one steady period of excitation. Total.
