Torsional sensor, method thereof, and system for measurement of fluid parameters

摘要

A torsional sensor (16) for sensing at least one parameter of a fluid (12) is disclosed. The torsional sensor (16) includes a torsional portion (20) coupled to a reference portion (18) and including a plurality of projections (38) extending outward and spaced apart from each other. At least a portion of the torsional sensor (16) is mountable for immersion in the fluid (12) and operable to propagate a torsional wave that interacts with the fluid (12) along the at least portion of the torsional sensor (16) so as to affect propagation of the torsional wave in a manner dependent on the at least one parameter of the fluid (12).
