摘要
Pairs of acoustic transducers positioned at different radial distances in a conduit are used to measure travel times of acoustic signals in opposite directions and inclined to the direction of a fluid flow in the borehole. These contrapropagation measurements are used to estimate fluid velocity and volumetric flow rates of the fluid components in the conduit.
