Abstract: Systems and methods of a transducer having a plastic matching layer. At least some of the illustrative embodiments are methods including providing a transducer housing having a proximal end and a distal end, and bonding a plastic to the distal end of the transducer housing (the plastic fluidly sealing and occluding the distal end). The bonding further includes inserting a cylinder comprising a mold-release chemical into the transducer housing, bonding plastic onto the distal end of the transducer housing, and removing the cylinder when the plastic has hardened.

Abstract: A transformer board is disclosed. In some embodiments, the transformer board includes a base, a circuit board, a transformer having a first and second winding, a first and a second connector, a ribbon cable and a nonconductive fill material. The base has a recess within which the circuit board is positioned. The transformer is mechanically coupled to the circuit board. The first connector is configured to electrically couple to transducers within a pressure boundary of an ultrasonic flow meter and is electrically coupled to the second winding of the transformer. The ribbon cable is electrically coupled between the first winding of the transformer and the second connector. The nonconductive fill material is contained by the recess and encases the circuit board, the transformer, the coupling of the first connector to the second winding of the transformer, and the coupling of the ribbon cable to the first winding of the transformer.

Abstract: Systems and methods of a transducer having a plastic matching layer. At least some of the illustrative embodiments are transducers comprising a housing (having a proximal end, a distal end and an internal volume, the housing configured to couple to a spoolpiece of an ultrasonic meter), a plastic matching layer that has an external surface and an internal surface (the plastic matching layer seals to and occludes the distal end of the housing), and a transducer element abutting the internal surface of the plastic matching layer.

Abstract: An extractor tool for an ultrasonic flow meter is disclosed. Some system embodiments comprise a bracket configured to couple to a spoolpiece of an ultrasonic flow meter and a tube inserted through and coupled to the bracket. The tube is configured to seal to the spoolpiece and permit a transducer to be selectively installed and removed therethrough.

Abstract: A cable cover for an ultrasonic flow meter is disclosed. In some embodiments, the cable cover includes multiple interlockable pieces configured to couple to a spoolpiece of an ultrasonic flow meter. Each interlockable piece includes a body having a dowel and a slot. The interlockable pieces are assembled in a series with the dowel of each interlockable piece inserted into the slot of another interlockable piece.
