Abstract:
1. A torsional sensor for sensing at least one parameter of a high-pressure fluid in a conduit, the torsional sensor comprising: a reference portion comprising a transducer device; a torsional portion comprising a torsional rod sensor coupled to the reference portion; a high-pressure sealing mechanism coupled to the reference portion and the torsional portion and in sealing arrangement therewith, the high-pressure sealing mechanism configured to provide for sealing therein the transducer device and allow for protrusion therethrough of the torsional rod sensor, the high-pressure sealing mechanism comprising: wherein the reference portion and the torsional portion of the torsional sensor are mounted relative to the conduit for immersion in the high-pressure fluid and operable to propagate a torsional wave that interacts with the high-pressure fluid along the at least portion of the torsional sensor so as to affect propagation of the torsional wave in a manner dependent on the at least one parameter of the high-pressure fluid.
