The use of a modified impact type of probe for velocity field measurement in the flow of multi-sized (d50=71 μm) particulate slurries is described. The impact probe has a sensor similar to a two hole offset probe but has a modified pressure sensing system which prevents blockage of the probe by the solid particles. The probe system has been successfully used in slurry flows over a wide range of solid concentrations (0–40% by weight) and flow velocities (1.67–2.95 m/s). The data presented in this paper have revealed some special features of velocity distribution in the flow of multi-sized particulate suspensions.
