An electrical capacitance tomography system (ECT) has been developed. The system consists of a circular sensor with 8 electrodes. A charge generator injects charges into the sensor filled with objects different dielectric constants. The charges, in the form of potential dropped, on another electrode are measured and acquired digitally to a PC for calculating the capacitance and estimating the d...

In this work we apply the simulated annealing (SA) inversion method to the reconstruction of permittivity images from electrical capacitance tomography (ECT) data. We test the SA inversion method using static physical models simulating some typical distribution patterns of two and three-component flows. The SA-based permittivity inversions have some advantages over other approaches based on lin...

The process of mining filling, when the slurry is transported to goaf by filling pipeline, very important find location and size caking in pipeline time for safe stable operation mine pipeline. It an research work detect different flow patterns after two-dimensional section reconstruction closed based on ECT (electrical capacitance tomography) visualization method. Slurry regarded as a two-phas...

Electrical capacitance tomography (ECT) is considered to be a competitive measurement method. The imaging objects in ECT measurements are often in a time-varying process, and exploiting the prior information related to the dynamic nature is important for reconstructing high-quality images. Different from existing reconstruction models, in this paper a new model that incorporates the spatial cor...
