CFD analysis of the ultrasonic gas meter channel

This paper describes a process of numerical testing and optimization the ultrasonic gas meter channel. A conventional flowmeter requires large installation space due to quality stability velocity profile. Previously, shape inner channel was optimized reach suitable flow field for measurement. The goal this work is find an optimal design reduced size achieve stable profile with minimum disturbances regardless entry conditions in smallest possible space. Flow characteristics volume rate range (1 250) m 3 /h were tested parameters adjusted. Obtained results show good match requirements. Future should aim measurement transit time measured values on design. Finally, it will enable create analogy between numerically obtained fields real
