Research on the Method of Parameter Estimation for Two-Phase Flow Rate Measurement

In order to solve the problems of low resolution and poor real-time perfomance in flow rate measurement by using correlation method, a new method of parameter estimation for two phase flow rate measurement is introduced in this paper. This method is based on polarity pilot self-adaptive algorithm. The hardware structure and operating procedures for implementing this algorithm are described in detail, and the result of intercomparison of these two methods for gas/water two phase flow measurement on a vertical pipe is given. The resolution and real time performance of this new method are better than those of the correlation method.
