A flowmeter has a one-piece conduit with an outer surface and an inner surface that define a wall thickness therebetween, and first and second transducers, where each transducer is disposed external of or integral with the one-piece conduit, in signal communication with an interior volume of the one-piece conduit, and relative to each other such that each transducer can send and receive an acoustic signal to the other transducer. The one-piece conduit includes a plurality of acoustic noise attenuating features integrally formed with at least one of the outer surface and the inner surface and disposed between the first and second transducers, each of the features being configured and oriented to disturb a propagation direction of a parasitic acoustic wave that will propagate in the wall of the one-piece conduit in response to activation of at least one of the transducers.
