A flowmeter with ribbed housings for accommodating transducers. The ribbed housings may be of a profile to attenuate or dampen acoustic noise which occurs as a transducer emits frequencies across housing walls toward a fluid flow path of the flowmeter. Thus, as transducers receive flow velocity date it may be collected for analysis in a manner that substantially eliminates the inclusion of noise within the data to be analyzed. Once more this is achieved in a manner that utilizes a monolithic housing in place of a segmented or multi-component housing that is prone to include polymeric and other parts subject to premature wear and failure.
