Algorithm Research on Velocity Measurement of Biphase Flow

In this paper, two-phase flow was taken as measuring object, the minimum sum error of squares method are proposed by capacitive velocity sensor. Velocity measuring principle is analyzed in theory. Through analysis and comparison of collected velocity signals in laboratory, The experimental results have known that the measurement technique features high precision, short measurement time and high reliability, and the method can satisfy the need of velocity measurement of two-phase flow. This offers an effective means for two-phase flow velocity measurement, too.
