【Abstract】 Based on the spatial filtering effect which occurs when oil/gas/water three phase liquid flow through the capacitance electrodes,the flow velocity in liquid and gas phase can be measured by frequency analysis?This method needs less measuring parameters and can be used to measure the component’s velocity in multi-phase liquid for demand of real-time,on-line,continuous and non-intrude.更多还原
