A Study of Differential Pressure Measurement in Vortex Flowmeter
Abstract
Vortex flowmeter based on pieazoelectric transducer is subjected to noise disturbances caused by pipe vibrations and fluid turbulence during measurement. According to the characteristics of the fluid field near the bluff body, the method using differential pressure between two sides of the bluff body to measure vortex frequency is presented in the paper. Numerical simulations have been carried out to help the optimally sensor structure design. The experimental results show that this method is effective to measure vortex frequency and has robustness to disturbances.
