Measurement and analysis of water/oil multiphase flow using Electrical Capacitance Tomography sensor

The paper investigates the capability of using a portable 16-segmented Electrical Capacitance Tomography (ECT) sensor and a new excitation technique to measure the concentration profile of water/oil multiphase flow. The concentration profile obtained from the capacitance measurements is capable of providing images of the water and oil flow in the pipeline. The visualization results deliver information regarding the flow regime and concentration distribution of the multiphase flow. The information is able to help in designing process equipment and verifying the existing computational modeling and simulation techniques.
