Abstract
A system and method for measuring the flow of water in cross-section of a body of water is presented. The system and method comprises a housing having a first transducer and a plurality of second transducers, wherein the first transducer produces an acoustic signal for determining the depth of the body of water, and the second transducers each produce an acoustic signal for determining the velocity of a volume of water by measuring the Doppler frequency shift in the returned echo.
