1. A transducer for non-invasive measurement, comprising:
a first piezoelectric element;
a second piezoelectric element;
a third piezoelectric element;
a fourth piezoelectric element; and
a base material configured to be mounted to a wall of a vessel that contains a liquid, the base material comprising a planar portion and an angular shaped portion, the angular shaped portion comprising a plurality of outer faces, including a first face and a plurality of second faces, the first face of the plurality of outer faces of the angular shaped portion being connected to a first face of the planar portion, a second face of the planar portion opposite to the first face of the planar portion being configured to be mounted to the wall of the vessel,
wherein a first one of the plurality of second faces is contiguous and angled to the first face of the plurality of outer faces of the angular shaped portion at an angle less than an angle of 90 degrees internal to the base material, and is angled to a second one of the plurality of second faces at an angle greater than an angle of 90 degrees internal to the base material,
wherein a third one of the plurality of second faces is contiguous and angled to the first face of the plurality of outer faces of the angular shaped portion at an angle less than an angle of 90 degrees internal to the base material, and is angled to a fourth one of the plurality of second faces at an angle greater than an angle of 90 degrees internal to the base material,
wherein the first piezoelectric element is mounted to the first one of the plurality of second faces,
wherein the third piezoelectric element is mounted to the third one of the plurality of second faces,
wherein the fourth piezoelectric element is mounted to the fourth one of the plurality of second faces, and
wherein the second piezoelectric element is mounted to the first face of the planar portion of the base material at a position adjacent to the angular shaped portion of the base material.
