Electrical Capacitance Tomography (Ect): Principles, Systems and Industrial Applications

Electrical capacitance tomography (ECT) is a non-invasive imaging technique that creates a cross-sectional image of the distribution of dielectric materials inside a pipe or vessel. ECT measures the capacitance between pairs of electrodes mounted on the outside, and reconstructs a cross-sectional image using the measured capacitance data and a suitable algorithm, to reflect the permittivity distribution within the object. The techniques is used to visualize the internal flow of non-conductive substances in industrial processes such as the chemical, oil and gas industries.

Written by a world-leading authority in electrical capacitance tomography (ECT), which he has taken from early laboratory feasibility studies in the 1990s to an established commercial technology today, this book gathers 30 years of expertise in the field. The book aims to describe the principles of ECT systematically, show how to build ECT sensors, introduce different capacitance measuring circuits suitable for ECT and image reconstruction algorithms, explore industrial applications in the pharmaceutical, chemical, process, power, gas, oil and water industries, and identify future perspectives and developments of ECT.

This book is a valuable advanced reference for researchers working on ECT technology for industry applications and other tomography modalities. It will also be useful to researchers and professionals in industry, who are using or plan to use ECT systems to visualise and measure industrial processes.
