1. A transducer assembly for a flowmeter, the assembly comprising:
a transducer to direct an acoustic signal past a wall of a transducer housing and toward an adjacent flow path of the flowmeter;
a plurality of attenuating ribs adjacent the transducer and physically coupled to the transducer housing at a location opposite that of the flow path, wherein a first rib of the plurality of attenuating ribs in closest proximity to the transducer housing is of a first geometry and a supplemental rib of the plurality of attenuating ribs adjacent the first rib is of a second geometry, and the first geometry differs from the second geometry in both diameter and width; and
at least one seal disposed between the transducer housing and a body of the flowmeter that provides metal to metal contact.
