A simulation software for Electrical Resistance Tomography (ERT) was set up, and was used for the measurement of two phase flow. The numerical value of the ERT sensitive field was calculated,the character of the ERT sensitive field was analysed, and the reconstruct tomography was obtained. The companison between the results of the simulation and theoretical solution shows they coincide, the error of even square root between them is within 1%, and the reliability was verified. Five typical two phase patterns were set up, the reconstruct images and the distribution of real conductivity were compared, and a reliable and advantageous way for the research of the properties and reconstruction algorithms of ERT was provided.
