Experimental studies are carried out on the cross-correlation velocity measurement of the gas-liquid two-phase flow based on twin-plane electrical resistance tomography.The principle of cross-correlation velocity measurement is analyzed.A cross-correlation velocity measurement method based on void fraction is proposed.The sample data for the void fraction of the upstream and downstream cross-section are increased by interpolation.Taking advantage of the data storage and playback function of the self-developed software system

the cross-correlation velocity measurement method based on void fraction is evaluated.Experiment results show that the cross-correlation velocity measurement method has good stability and high precision.
