Abstract: this study a theoretical investigation of performance of multipath ultrasonic flow meters under distorted flow profiles is proposed. The velocity distribution depends on the pipe configuration, which will produce an asymmetric flow profile and as a result will affect the accuracy of measurement. So, we discover how to minimize the effect of distorted flows on measuring process of ultrasonic flow meters due to number of chords and their arrangement. In order to evaluate the performance of the multipath ultrasonic flow meters the measurement error is determined for various asymmetric flow profiles with different chord configurations. As a part of the work it was obtained strategy that can reduce the error associated with different flow disturbances. Using CFD analysis interesting conclusions have been derived. These conclusions can be applied to specific individual situations and a significant reduction in error can be achieved.
