Abstract A three-segment direction specific probe based on the electrodiffusion measuring technique was used to measure local liquid velocities in gas-liquid flow. Dissolved oxygen was employed as depolarizer instead of the usually applied redox system ferro-ferricyanide in water. The concentration of the auxiliary electrolyte K2SO4 was so low that coalescence behaviour of the gas-liquid system was not influenced. It was possible to measure liquid velocities up to ca 100cm s−1. The probe showed satisfying sensitivity to flow direction. Furthermore, unequivocal discrimination between signals from the liquid and gas phases was achieved.
