A sonic flow meter in the form of a conduit providing a linear fluid flow path and having first and second openings on opposite sides of the conduit displaced in an upstream-downstream relationship providing a sonic path through the interior of the conduit, with sonic transducers elements positioned to transmit and receive energy through the sonic path, and having an upstream and downstream flow straightener for separating the fluid stream into a plurality of reduced-cross-sectional area streams, ends of the flow straightener being in planes paralleling, and adjacent the sonic path.

A sonic flowmeter comprising: a conduit having an inlet end and an outlet end, and providing a linear fluid flow path therebetween; a first and a second opening in said conduit, the openings being in a plane of the conduit longitudinal axis and on opposite sides of the conduit, the openings being displaced in an upstream-downstream relationship providing a sonic path through the interior of the conduit, the sonic path being at a preselected angle to the conduit linear fluid flow path; first and second spaced apart transducer elements positioned to transmit and receive sound energy traveling through fluid as it traverses said conduit; an upstream flow straightener within said conduit fluid flow path for separating the fluid stream into a plurality of reduced-crossectional area streams, each providing a separate linear fluid flow path, the flow straightener having a forward end and rearward end, the rearward end being contiguous to and in substantial conformity with said sonic path.
