Keywords: Conductivity probe air fraction calibration rig
Abstract: This study presents the calibration of air-water single-tip conductivity probes, made of copper using diameters from 0.2 to 0.6mm, to measure the fraction of air in two-phase flows. The calibrations were performed on a specialized rig, which allows the generation of controlled concentrations of air in water. The results show that the smaller diameter tips offer greater sensitivity in the detection of bubbles and accurate measurement of the air fraction, especially in flows with high turbulence. Fourth degree polynomial calibration equations were obtained for each probe and that allow to adjust the air fraction measurements to the real values obtained in the calibration rig.
