A conductometric sensor system for detecting HS-CAP was constructed by incorporating the screen printed electrodes covered with MIF into electrode slots of a conductometer.

The technical indexes of LS type conductance sensor with no electrode are introduced.

Wigner-Ville analysis of measurement fluctuating signals of conductance sensor in gas/liquid two-phase flow;

For the water volume fraction measurement of oil-in-water flow,the mathematical model for the forward problem of sensitivity field in the ring-shape four-electrode conductance sensor was analyzed.

An embedded real-time microprocessor MC56F8323 is used for sampling two fluid flowing signals of conductance sensor's output, calculating cross-correlation function of these signals, and finally transferring the flowrate up to the host computer on the ground through RS485.
