SENSOR APPARATUS AND METHOD FOR MEASURING FLOW
First Claim
1. A transducer device for mounting to an external surface, comprising:
- an elongated transducer waveguide;
wherein the elongated transducer wave guide is coupled via a neck region to a distal end;
wherein the neck region is substantially shorter than the elongated transducer waveguide; and
wherein a thickness of the elongated transducer waveguide is substantially similar to a thickness of a wall to which the waveguide is mounted.

Abstract
A sensor apparatus is provided for measuring within a region of a conduit for guiding a flow. The apparatus includes a transducer arrangement disposed at least partially around an external surface of a wall of the conduit and having one or more driver elements for exciting in operation a helical acoustic wave propagation within the wall of the conduit for leaking acoustical energy from the helical acoustic wave propagation over an extensive area of the wall of the conduit for stimulating waves in chordal paths within the flow, wherein the waves in the choral paths within the flow reenter the wall of the conduit to propagate further as a guided helical wave. The transducer arrangement includes one or more sensors for receiving a re-entered portion of the acoustic wave propagation along the paths within the flow which interacts with the flow and includes information characterizing properties of the flow.
