Abstract: A flow meter includes a pair of ultrasonic transducers. Each transducer includes a housing, a piezoelectric crystal disposed within the housing, and a mini-horn array coupled to the housing. The mini-horn array, which may be formed via a 3D printing technique, includes an opening-free enclosure, a closed cavity inside the enclosure, and a plurality of horns enclosed within the closed cavity. The horns include a horn base portion adjacent to a proximal end surface of the cavity and a horn neck portion that extends from the base portion in a direction away from the piezoelectric crystal and towards a distal end surface of the cavity. The horn neck portions are separated by spaces within the cavity, wherein the spaces between the horn necks may be filled with powder.

Abstract: A flow meter includes a meter body having a longitudinal axis and including a fluid passageway and an outer surface, and a plurality of electronics housings supported on the meter body by a mounting member, wherein the mounting member includes a base, a tubular member having a passage extending therethrough for the passing of a transducer cable, and a bracket member coupled to the tubular member distal the base, the bracket member having a pair of elongate slots, each configured to allow for the passage of a transducer cable to one of the electronics housings.
