“…However, because water itself has low conductivity, it may not be the most suitable liquid phase in some situations; increasing its conductivity by the adding a salt (e.g., NaCl, KCl) can provide better measurement accuracy [74,96,[102][103][104]. With respect to the non-conductive phase, several types of particles have been used in the works reported in the literature: among these are studies using glass, nylon or plastic beads [102,105], lava rock [106], quartzite particles [102], sand [107], and silica [108].…”

“…Two-phase systems in which both phases are liquids with different conductivities also comprise an important research area, particularly when one of them is an oil. In the literature, there are mentions of the use of linseed oil [111], shell sol D70 [97], sunflower oil [108], and paraffin oil [112,113], among others. In the food industry domain, the dairy industry also presents great potential for the application of electrical tomography.…”

Understanding the behaviour of suspension flows continues to be a subject of great interest considering its industrial relevance, regardless of the long time and effort dedicated to it by the scientific and industrial communities. Information about several flow characteristics, such as flow regimen, relative velocity between phases, and spatial distribution of the phases, are essential for the development of exact models for description of processes involving pulp suspension. Among the diverse non-invasive techniques for flow characterisation that have been reported in the literature for obtaining experimental data about suspension flow in different processes, Electrical Tomography is one of the most interesting, since it presents perhaps the best compromise among cost, portability, and, above all, safety of handling (indeed there is no need to use radiation, which requires special care when using it). In this paper, a brief review and comparison between existing technologies for pulp suspension flow monitoring will be presented, together with their strengths and weaknesses. Emphasis is given to Electrical Tomography, because it offers the above-mentioned compromise and thus was the strategy adopted by the authors to characterise different flow processes (solid–liquid, liquid–liquid, fibres, etc.). The produced portable EIT system is described, and examples of results of its use for pulp suspension flow characterisation are reported and discussed.
