A system includes a transducer assembly for a flowmeter. The transducer assembly includes a housing with a front face and at least one attenuating rib. The transducer assembly also includes a transducer positioned in the housing and configured to direct an emitted acoustic signal through the front face of the housing and into a flow path of the flowmeter and to receive a received acoustic signal through the front face of the housing. The system also includes a controller configured to use the received acoustic signal to determine a ratio of a first component versus a second component in a gas flowing through the flow path of the flowmeter.

Flowmeter with attenuating ribbed transducer housings

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 data, 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.

An assembly for monitoring particulate in a production fluid. The assembly supports routing of production fluid through a restriction and to a strategically located detector downstream and adjacent the restriction. Further, the detector incorporates acoustic attenuating features to provide a tailored detection focused on acoustics directly from particulate in the fluid. These features may include the use of a transducer housing with a ribbed profile to achieve the attenuation. Although, other types of attenuating techniques may be employed.
