The utilization and application of a desk-top micro-computer based system is described for data acquisition and control/or use in the velocity measurements in open channel flow. The technique of measuring point velocities along three axes simultaneously is approached in two phases: Firstly,recording of the velocity data, and secondly reproducing the velocity data. The system involves utilization of voltage data recorder which can translate the flow velocities obtained by sensor probes picking up the acoustic interference. A data acquisition control unit, a desk-top computer and peripheral equipments which consist of distribution channels, printer and plotter terminals provide the necessary interpretation of the flow behaviour.
