Abstract
A process flow device includes a self-averaging pitot tube type of primary flow element for measuring, by a differential pressure process, the volumetric rate of fluid flow at a point in a fluid carrying conduit where the velocity profile of the fluid is asymmetric with respect to the longitudinal axis of the conduit. The improved flow element comprises an annulus having a central opening and a pitot tube type flow-impeding device disposed transversely across the central opening and perpendicular to the longitudinal axis of the conduit. The pitot tube type flow-impeding device includes a plurality of total pressure ports in an upstream facing surface, a plurality of static pressure ports in a downstream facing surface, and total and static pressure plenums connected in fluid communication respectively to the total and static pressure ports.
