The invention discloses an Electrical Tomography (called ET for short) two-phase flow measurement system which is applicable to conveying working conditions of real-time variations of liquid medium characteristics in two-phase flow media. The system comprises an ET sensor, an additional reference point measurement device and a signal generation and data collection processing system. The additionalreference point sensor and the ET sensor are placed in a same conveying pipeline system and have a function of conducting real-time measurement of a characteristic value of a dilute phase liquid medium in the two-phase flow media and providing a reference basis for ET, and through judgment of sensitive field characteristic distribution of the ET sensor, the characteristic value of the reference point medium can be offset in real time, and distribution of the two-phase media is obtained; and a resistive layer tomography sensitive field characteristic is conductivity, and a capacitance tomography sensitive field charac
