A Sequential Ultrasound and Electrical Capacitance Process Tomography Sys- Tem
Abstract A novel concept for the fusion of Ultrasound Reflection Tomography (URT) and Electrical Capacitance Tomography (ECT) for industrial process applications is presented. The method is intended to combine the strengths of both principles while reducing their respective disadvantages. ECT is sensitive to bulk rather than to phase boundaries and suffers from blurred images. URT is able to de...
متن کاملApplication Research of Wavelet Fusion Algorithm in Electrical Capacitance Tomography
Electrical capacitance tomography (ECT) technology has the softfield nature and the ill-posed problems. To solve the problem of low imaging quality by standard Tikhonov regularization, a wavelet fusion algorithm based on Tikhonov regularization is proposed in this paper. Firstly, Tikhonov regularization method is used to solve ill-posed characteristic of system inverse problem, then the initial...
متن کاملElectrical Capacitance Tomography System
Electrical Capacitance Tomography is a non intruding technique used in industries. It is based on measuring the capacitance of multi-electrode ECT sensor produced by the change in dielectricity or due to change in concentration of material. With the use of computed values, a cross sectional image of the material placed in the dielectric medium is obtained. ECT system can be used in chemical fie...
متن کاملMass Flow Measurement of Biofuels using Electrical Capacitance Tomography
Biomass provides 10% of the global energy supply and electricity generation from biomass and waste is expected to increase by a factor of 4 by 2030. Currently efficiency of biomass power generation is poor and IEA targets improvements from 18% to 25% by 2030 [1]. Such increases in efficiency will require significant new technology and accurate real-time measurement of the flow of these highly v...
متن کاملElectrical Capacitance Tomography with a Square Sensor
Abstract – In the past, electrical capacitance tomography (ECT) with circular sensors has been extensively investigated. For some industrial applications such as circulating fluidised beds, square sensors are required. Research into this specific area has been carried out at UMIST for the first time. To generate sensitivity maps, the Laplace equation is solved using a finite difference method (...
