Abstract
A measurement apparatus for non-invasively logging the flow of perforations in a well casing lining a wellbore. The measurement apparatus includes a plurality of transducers arranged adjacent an outer surface of the measurement apparatus and at predefined azimuthal angular positions with respect to a longitudinal axis of the measurement apparatus, where the transducers are adapted to transmit and detect an acoustic pulse, and where each transducer is arranged at a different azimuthal angle with respect to each of the remaining transducers.
