Abstract: 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.

Abstract: A sensor for monitoring CO2 in a fluid regardless of the phase properties of the fluid, i.e., regardless of whether the fluid contacting the window is a liquid water-based phase, a liquid oil-based phase, a mixture of liquid water and liquid oil-based phases, or a gas phase. The sensor includes an internal reflection window for contacting with the fluid. A mid-infrared light source directs a beam of mid-infrared radiation into the window and the beam is internal reflected at an interface between the window and the fluid. The reflected beam is passed through three narrow bandpass filters which preferentially transmit mid-infrared radiation over bands of wavelengths corresponding to absorbance peaks of water, oil and CO2. The amount of CO2 is determined from the intensities of the mid-infrared radiation passing through the three filters.

Abstract: 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.
