| Abstract: | The experiment of water/gas, water/oil flow in vertical tube by using capacitance sensors and cross correlation anaysis was performed. The fluid physical properties and flow patterns that affect flowrate measurement were discussed as well. Two electrodes are placed around a vertical tube to collect the fluid signals. The different physical properties and void fraction of flow result in different sensors output.Through the cross correlation analysis between up and down stream sensors, an equation predicting the flowrate is proposed. The feasibility and reliability of this measuring method are verified by experimental results. |
