摘　　要：在油水两相流测量中,利用电容传感器和电导传感器在含率测量上有不同的敏感范围,设计一种电容电导传感器,使用电子开关实现两种测量方法的快速切换,使其在相同敏感场内测量。新型电容电导传感器实现了对水平管道内低电导率水(自来水)组成的油水两相流的全含率范围的测量,利用快关阀进行标定,其含率测量误差小于±5%。In oil-water two-phase flow measurement, a capacitance-conductance sensor has been designed based on the fact that the capacitance sensor and conductance sensor realize the water holdup measurement in different situations with different sensitive ranges. Electrical switches are used to switch the two measurement methods at high speed in order to make them have the same sensitive fields. The disigned sensor realizes the whole fraction measurement in oil-water two-phase flow with low conductivity water （tap water） and the water holdup measurement error is less than 5%.
