Optimized techniques for generating and measuring toroidal vortices via an industrial vortex flowmeter

摘要

A vortex flowmeter may utilize a ring-shaped bluff body as the vortex generator or shedder. The ring shape and size of the vortex ring generator may be optimized to produce linear and stable toroidal vortex outputs that may outperform the conventional shedder bar. In comparison to the conventional vortex shedder bar, the ring may have a slimmer configuration and a higher K-factor, and hence, a higher resolution.

1. An apparatus comprising:
a conduit body comprising a flow of at least one fluid therein; a ring-shaped bluff body disposed within the conduit body and configured to produce toroidal vortices within the flow of the at least one fluid; at least one support attaching the ring-shaped bluff body to the conduit body; and at least one transducer disposed adjacent to the at least one support to detect drag induced pulsating mechanical effects on the at least one support.
