The application of micro process tomography to microchannels is considered in this paper. Using the micro process tomography system in microchannel, a particle distribution image can be obtained in a two phase flow. Based on the reconstructed image, it is easy to estimate the particle movement in a fluid flow. A novel microchannel system is designed for electrical process tomography that includes 60 electrodes distributed cross-sectional at five positions. The particle and water were injected into the microchannel, and then the capacitance of the fluid flow was measured at cross-section of microchannel. The result showed the 2D image of particle distribution of cross-section in the microchannel. Also, cross-sectional images of the particle distribution of a two phase flow are simulated.
