英文摘要：

Measurement of gas/liquid two-phase flow parameters is of great importance to the control and optimization of industrial process. The precision of two-phase flow modeling is directly affected by the component fraction. A measurement system based on concave-shaped electrode conductance sensor is designed to measure the fraction in two-phase flow. Static calibration of typical flow pattern simulation shows that relationship between liquid fraction and measuring voltage is linearly related in gas/liquid two-phase flow. It provides basis for dynamic experimental measurement.
