Research of Ultrasonic Flow Detection Method Based on Hydrodynamics Analysis

Abstract:

Commonly referring to the flow velocity is surface mean velocity which evenly be distributed along the circular cross section of pipe. But the pipe velocity measured by ultrasonic flowmeter is linear mean velocity along ultrasonic transmission routes. They are different, so must be corrected. Using the hydrodynamics theory, this paper deduced the equation of flow correction coefficient in laminar flow condition and turbulent flow condition, and dynamically dealt with flow correction coefficient, finally analyzed and evaluated correction curves. The results indicate that this paper can accurately calibrate the ultrasonic flow and get the satisfactory measurement results.
