Research and Optimization on the Venturi Tube Dynamic Throttling Element of New Flowmeter


Article Preview

According to the working process of dynamic throttling element flowmeter, the Reynolds number keeps constant when the flow is steady. The way to change the pressure drop is to change the local pressure loss. Based on the Fluent software, analyze how the structure parameters of venturi tube affect pressure drop. With the completion of flowmeter prototype, test the dynamic throttling element by using a kind of binary flow calibration platform. According to the test result, figure out that the optimization can perfectly meet the real flowing condition.
