In one embodiment, a multi-path ultrasonic flow meter for determining the flow rate of a fluid in a conduit is disclosed comprising at least two transducer pairs attached to the conduit at two chord locations, one greater than and one less than a mid-radius chord, wherein the composite ratio the two path velocities to the flow rate is substantially constant over the range of Reynolds numbers. In another embodiment, a method of determining the flow rate of a fluid in a conduit is disclosed comprising the steps of determining a composite velocity by determining a weighted average of a plurality of path velocities, determining a chord velocity ratio based on the path velocities, determining a profile correction factor based on the composite velocity and the chord velocity ratio, and determining the flow rate based on the composite velocity and the profile correction factor.
