Abstract
An acoustic system for measuring the speed of flow or current speed of a body of water employing a measuring path through the water which extends from one shore to the other in a direction oblique to the direction of flow of the water. A triggerably measuring sound generator positioned on one shore transmits a pulse over the measuring path to a receiver on the other shore. The receiver produces an output which triggers the measuring sound generator to emit a subsequent pulse. A measuring circuit evaluates the resulting pulse repetition frequency of pulses emitted by the sound generator and produces an output proportional to the flow speed of the water.
