英文摘要： This project aims at the design and implementation of a multisensory (electrical and ultrasonic sensor-array) instrument providing the visualization and measurement of oil-gas-water multiphase flow that frequently encountered in petroleum and chemical engineering industrial processes. The proposed instrument is re-configurable, frame-style and flexible in hardware, and also modular, multi-process and extensible in the dedicated software. This instrument is developed based on but beyond the past work on measuring instrument, and is dedicated to the time-variant multiphase flow situation with the philosophy of flexible system structure both on hardware and software. A high performance universal testing platform is built with the advantages of fast response, accurate measurement, as well as high extensibility and adaptability, all in the frame of standardization and modularization design. Heterogeneous information from multiple sources of electrical and ultrasonic sensors is optimally configured to accomplish the fusion characterization as well as the cross-sectional image reconstruction of multiphase flow. The process information of multiphase flow is effectively extracted, in a flow-condition-free and wide-range manner, basing on the fusion of electric/acoustic impedance information and environmental process comp
