Abstract:
     The present invention relates to a capacitance-type two-phase flow phose-concentration meter and its measuring method, belonging to an industrial detection apparatus and its measuring method. The phase concentration measurement is an important problem met in two-phase flow industrial detection and laboratorial study. Said invention recommends a phase concentration meter which isn't sensitive to the variation of flow pattern and its measuring method. It is characterized by that uses a multielectrode capacitor transducer with a ring shaped structure and passes through an optimization of electrode structural size so as to form an everywhere uniform distribution of measuring sensitivity on the cross section of a current-carrying pipeline, and under this prerequisite it can realize the rotational measurement a round pipeline axle centre and use the average value of measurement values of various rotation angles as the phase concentration signal.
