Abstract: One of the findings from the 2012 NSFMW paper Limits of Achieving Improved Performance from Gas Ultrasonic Meters and Possible Solutions 1 was that increasing the number of paths beyond 4 has little effect on the integration. In the paper, the power law profile was used to make this assertion and a specific type of Gaussian quadratur e. It appears that the original intent may have been to illustrate whether more chords offer much improvement in the integration . It was therefore decided to model the effect of mor e chords on the integration in the presence of axial asymmetry and no swirl for two different methods of Gaussian quadrature and see if this conclusion still holds true .
