Accurate measurement of flow parameters is important in gas-solid two-phase flow, and such flow has to be dealt with in many processes involving bulk solids handling and transportation. The circular electrostatic sensor is one of those used for gas-solid flow measurement. This paper uses the finite element method to establish the mathematical model of the sensor, the spatial sensitivity of the sensor were studied. The analytic model is optimized by nonlinear least squares method and iterative method. Finally, the correlation coefficients between the experimental results and the optimized processing are compared and analyzed, and the mathematical expression of the model is improved. The feasibility and practicability of the optimization model are verified.
