A novel method for the two-phase flow measurement based on the multisensor fusion system of electrical resistance tomography (ERT) and the electromagnetic flowmeter is proposed. As important research content of the multisensor fusion system, the ac impedance model of the array electrodes of ERT is set up and analyzed based on the principle of the electrochemical properties of the sensing electrode material in the two-phase flow. The model can provide theoretic guidance for the design of new-generation ERT systems and the study of multisensor fusion systems.
