Techniques for determining the properties of bubbles in bubble columns . Three different methods for the determination of bubble size parameters namely (i) flash‐photography followed by image analysis, (ii) use of a conductivity probe with two electrodes and electronic processing of the signals, and (iii) the electro‐optical probe with the same signal processing as the conductivity probe are compared and contrasted from the viewpoint of their optimal use, their accuracy, and their scope of application.
