Theoretical and Experimental Analysis of Ultrasonic Cross Correlation Flow Measurement Technology

Abstract

Advanced Measurement and Analysis Group Inc. (AMAG) is a developer and manufacturer of the non- intrusive ultrasonic cross correlation flow meter CROSSFLOW, which is installed in nuclear reactors in Canada and around the world. To meet growing demand for better accuracy, AMAG and De Montfort University started a joint project to develop a mathematical model of the meter, based on turbulence dynamics. In the first year, a simplified model was developed. Predictions made by this model were confirmed by conducted experiments and computational flow simulations. The model can be used to predict the effect of flow disturbances on meter readings.
