Claim Text:
1. An apparatus comprising: a ring-shaped bluff body configured to produce toroidal vortices when the bluff body is disposed within a flow of at least one fluid, wherein the bluff body further comprises: at least one transducer disposed adjacent to the ring-shaped bluff body to detect one or more mechanical effects induced by the toroidal vortices, wherein the at least one transducer is shielded from contact with the at least one fluid, wherein the at least one transducer comprises a first strain transducer to detect a cavity wall strain resulting from stress acting on a first side of the tongue and a second strain transducer to detect a cavity wall strain resulting from stress acting on a second side of the tongue, wherein the first strain transducer and the second strain transducer are coupled to a sensor body and are each disposed at least partially within the cavity.
