Electrical capacitance tomography (ECT) is a non-intrusive and 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 of the pipe, and reconstructs a cross-sectional image using the measured capacitance data and a suitable algorithm, to reflect the inside permittivity distribution. ECT is particularly useful for visualising the multiphase flow of non-conductive substances in industrial processes.
Written by a world-leading authority in 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 make ECT sensors, introduce different capacitance measuring circuits suitable for ECT and image reconstruction algorithms, explore industrial applications in the pharmaceutical, chemical, process, power, gas and oil industries, and identify future perspectives and developments of ECT.
Electrical Capacitance Tomography (ECT): Principles, systems and industrial applicationsis a valuable advanced reference for researchers working on ECT for industrial applications and other tomography modalities. It will also be useful to researchers and professionals in industry, who are using or intend to use ECT to visualise and measure industrial processes.
