Abstract:
The measurement characteristics of vortex flowmeter are researched in two-phase flow under the conditions that water is a continuous phase and gas is a discrete phase which is injected into the fluid.The experiment is done in a 50mm-diameter level pipe when the water volume is during 6~12 m3/h and the gas volume fractions are during 3%~15%.The vortex flowmeter measures water volume by spectral analysis and pulse counting simultaneously and these two measurement modes are compared.The effects of different gas volume fractions on measurement error of vortex flowmeter are analyzed by processing experimental data.
