Abstract:
An electromagnetic flow meter comprises a magnetic excitation coil, first and second electrodes which are disposed opposite to each other on an outer peripheral surface of a measurement tube, an amplifying circuit that amplifies an electromotive force generated between the first electrode and the second electrode, a flow rate calculation portion that calculates a flow rate of the fluid, a third electrode formed on the outer peripheral surface of the measurement tube separated from the first electrode and the second electrode, a fourth electrode which is in contact with the fluid, a resistor in which one end is connected to the third electrode, a voltage detecting portion that measures voltages of a signal generated in the third electrode by inputting an AC signal to the other end of the resistor, and an electrical conductivity calculating portion that calculates electrical conductivity of the fluid.

Claim (Index 1):
An electromagnetic flow meter comprising:\n a measurement tube which is formed of an electrical insulation material and through which a measurement target fluid flows; a magnetic excitation coil which is disposed outside the measurement tube and generates a magnetic field according to a supplied AC current; a first electrode and a second electrode which are provided on an outer peripheral surface of the measurement tube and are disposed opposite to each other in a direction perpendicular to the magnetic field generated from the magnetic excitation coil; an amplifying circuit that operates with a common potential as a reference and outputs a signal obtained by amplifying an electromotive force generated between the first electrode and the second electrode; a flow rate calculation portion that calculates a flow rate of the measurement target fluid based on a signal output from the amplifying circuit; a third electrode which is formed on the outer peripheral surface of the measurement tube to be separated from the first electrode and the second electrode; a fourth electrode which is connected to the common potential and is in contact with the measurement target fluid; a resistor of which one end is connected to the third electrode; a voltage detecting portion that measures voltages of a signal generated in the third electrode by inputting an AC signal to another end of the resistor; and an electrical conductivity calculating portion that calculates an electrical conductivity of the measurement target fluid based on an amplitude of the voltages measured by the voltage detecting portion.
