Abstract

This paper presents the first results of dynamic flow measurements using rotatable ECT sensor. The experiment has considered horizontal flow in a pneumatic conveying flow loop in the case of dense phase flow. Slugs and settled layers are imaged and comparison is done between no rotation or rotation of the sensor for 2 image reconstruction scheme: LBP and iterative non­linear LBP. Data are evaluated both qualitatively and quantitatively by estimating the solids concentration level for different hue levels.
