Abstract
A transducer for use in measuring the sound velocity characteristics of a fluid medium formed of a transducer body having an access end and an opposed active end, the body having spaced apart first and second cylindrical openings therein extending from the access to the active end, a first and second acoustic window member sealably closing each of the cylindrical openings in the body at the active end, first and second transducer crystal elements within, respectively, the first and second openings and in sonic contact with the respective window acoustic members, a sound reflector affixed to the transducer body at the active end providing a first target surface coincident with the cylindrical axis of the first opening and providing a second target surface coincident with the cylindrical axis of the second openings, the target surfaces being spaced from the body active end and each being in a plane inclined toward the other defining a sonic path from the first acoustic window member to the first target surface, from the first target surface to the second target surface and from the second target surface to the second acoustic window member and a longitudinal slot formed in the body between the cylindrical openings providing acoustic isolation between the crystal elemens.
