An improved sonic flowmeter having a conduit with an inlet and outlet through which fluid flows for rate measurement, a portion of the conduit providing a linear flow path, a first and second spaced apart transducer element positioned to transmit and receive energy traveling through fluid as it traverses the linear flow path, circuitry connected to the transducer elements for detecting the speed of sound transmission between the transducer elements as an indication of the rate of fluid flow through the linear flow path, and dividers within the linear flow path separating the fluid stream into a plurality of reduced cross-sectional area streams, each providing a separate linear flow path through which sound is transmitted between the transducer elements providing means of increasing the linearity and repeatability of the detected rate of fluid flow.
