Claim 3:
4. The fluid flow conditioning apparatus of claim 2, wherein the sensor apparatus comprises:
a sensor housing having an interior surface defining a sensor axis and an axial interior sensor housing cavity comprising:
a first axial sensor housing portion having a first cross-sectional area perpendicular to the sensor axis;
a second axial sensor housing portion arranged adjacent to the first axial sensor housing portion along the sensor axis and having a second cross-sectional area larger than the first cross-sectional area perpendicular to the sensor axis; and
a face extending from the interior surface of the first axial sensor housing portion to the interior surface of the second axial sensor housing portion;

a buffer rod having a first axial end and a second axial end opposite the first axial end and comprising:
a first axial buffer portion arranged within the first axial sensor housing portion and comprising the first axial end;
a second axial buffer portion arranged within the second axial sensor housing portion and abutting the face, and comprising the second axial end; and
a third axial buffer portion, extending axially between the first axial buffer portion and the second axial buffer portion, and having a third cross-sectional area, smaller than the first cross-sectional area, perpendicular to the sensor axis;

a cavity defined between the interior surface and the third axial buffer portion; and
an acoustic transceiver element acoustically mated to the first axial end.
