Patent ID: 7533579

Claim:
A vortex flowmeter body adapted for use within a process fluid flow conduit configured for conveying process fluid in a downstream direction therethrough, said flowmeter body comprising: a tubular fluid inlet configured for being coupled in series to an upstream portion of the conduit; said fluid inlet fairing into a central bore having a transverse cross-sectional dimension less than that of the conduit; a shedder disposed within said central bore; said central bore communicably coupled to a tubular fluid outlet; said fluid outlet configured for being coupled to a downstream portion of the conduit; said fluid inlet having a stepped inner wall, including a first wall portion disposed at first angle to the downstream direction, and forming a substantially abrupt intersection with a second wall portion disposed at a second angle to the downstream direction; said second angle being greater than said first angle, wherein said first and second wall portions form a substantially rectilinear, concave axial cross-section.
