Abstract

This paper summarizes the basic principle of correlation method in the flow velocity measurement, and then advances an improved algorithm of polarity correlation method. Since then has carried on the algorithm analysis of polarity correlation method and circuit implementation. Based on the Monte Carlo method of the simulation experiments show that the polarity correlation algorithm can replace the common correlation algorithms on the peak point determination, and due to the particularity of its algorithm, it has good anti-interference function. The comparison of experimental measurement speed and speed setting by the Monte Carlo method shows that if the two sampling sensor spacing meet certain conditions, the measurement speed and its fitted curve could have a better Goodness of Fit, and the measurement speed can accurately response the speed setting by the Monte Carlo method. According to the experiment it can validate the feasibility of the algorithm, which could have an accurately measurement on flow velocity.
