The performance of a single path ultrasonic flowmeter is influenced by disturbance of the valve and the pipe fitting in the pipe line. In this paper describes flow performance prospects for a single path ultrasonic flowmeter. The single path ultrasonic flowmeter was installed before and after butterfly valve. Computational fluid dynamics (CFD) are used numerically to predict performance of ultrasonic flowmeter due to installed a butterfly valve in the pipe line. The simulations are carried out for several operating conditions, open rate of disk, velocity of fluid, and the distance between the flowmeter and valve. The results show that the disturbance of butterfly valve are one of the main reason for flow rate error. |
