Ultrasonic Tomography: Non-Invasive Techniques for Flow Measurement

This book presents a detailed study on ultrasonic tomography, including the principle, design and development. The ultrasonic tomography system comprises 16–pairs of ultrasonic transducers, the electronic measurement circuits, the data–acquisition system and several image reconstruction algorithms.The measurement of the flows was conducted in real–time. The system was capable of visualizing the internal characteristics of liquid and gas flow and provides the concentration profile for the corresponding flows. The results obtained are useful for online monitoring of liquid/gas flows for flow regime identification, chemical mixture transportation or fluid transportation at sub–sea oil fields.
