Abstract: The measurement of gas-solid two-phase flow’s parameters is an internationally recognized problem.
Based on the electrostatic sensing principle, gas-solid two-phase flow measurement’s research situation and apparatus
constructed to support the study are reviewed in this paper. As to the research situation, particle velocity measurement,
concentration measurement, electrostatic sensor’s model and measurement mechanism are described. As to the research
apparatus, simulation and real flow apparatus are introduced. Finally, it is concluded that this method can be used to
