Abstract

The object of this paper majors in the research of 8-electrode oil-water two-phase flow electrical capacitance tomography system. The distribution models of transducer's field are established by the finite element method for the influence of the parameters of transducer's structure on the performance of transducer. The analyses of simulation and experiment and the transducer's design optimized are done, and the measure function of transducer's design optimized is proposed based on transducer parameters. The system of 8-electrode oil-water two-phase flow electrical capacitance tomography is designed based on the results of theory and simulation analyses. The sensitivity and uniformity of sensitive field is improved and the design of the measurement circuit is easier but the data precision of sensitive field is enough for image reconstruction.
