• The present report describes a measurement technique for the determination of bubble size distribution in a bubbly flow. Electrical proves with two electrodes A and B located at a distance d_1 in the flow direction, or at right angles to the flow direction are used to detect the void signal A ∩ B when both electrodes A and B touch a bubble. The measurement is carried out in the case of air bubbles being ejected from void generators made of sintered metal element with multi-nozzles. The result shows that the bubble size distribution and mean bubble size data agree well with the data obtained by a photographic method.
