Abstract An electrodiffusional three-segment probe was developed with which local axial and radial liquid velocities can be determined. Application of this probe in gas-liquid flow yields information on local gas hold-up. In coalescing media the commonly used redox-system Fe(CN) 6 3− /Fe(CN) 6 4 should be replaced by dissolved oxygen as depolarizer. Measurements of local axial and radial liquid velocity and turbulence intensity in different bubble columns (D = 150 and 600 mm) showed good agreement with data obtained by hotfilm anemometry.
