Conductance sensor array is widely used in measuring two-phase flow parameters, in this paper we propose a new configuration of conductance sensors with six rectangular electrodes of same size from the pipe facing to an inner ring-type electrode and use it to measure gas cross-sectional-averaged water holdup value. The designed six rectangular electrodes are axially flush-mounted on the inside wall of an insulating duct. The geometry of six electrodes conductance sensor was determined with finite element numerical analysis. Sensor optimization of the electric field such as uniformity, spatial sensitivity is proposed. This configuration can improve measurement accuracy, through analyze sensitivity distribution, the role of soft field is discussed, and acquired the final size of the electrodes in the end. The simulation results were obtained from COMSOL Multiphysics finite element software. [ABSTRACT FROM AUTHOR] |
