20080276724 | SYSTEMS AND METHODS OF A TRANSDUCER HAVING A PLASTIC MATCHING LAYER - 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. | 11-13-2008 |
20080307911 | Cable Cover for an Ultrasonic Flow Meter - 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. | 12-18-2008 |
20090044635 | Extractor Tool for an Ultrasonic Flow Meter - 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. | 02-19-2009 |
20090174514 | Transformer Board - 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. | 07-09-2009 |
20090235501 | SYSTEMS AND METHODS OF A TRANSDUCER HAVING A PLASTIC MATCHING LAYER - 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. | 09-24-2009 |
20120067135 | ULTRASONIC FLOW METER WITH A LIQUID DRAINAGE SYSTEM - An ultrasonic flow meter for measuring the flow of a fluid through a pipeline comprises a spool piece including a throughbore and a transducer port. The transducer port extends along a central axis from an open end at the throughbore to a closed end distal the throughbore. In addition, the flow meter comprises an acoustic transducer disposed in the transducer port. The transducer includes a piezoelectric element. Further, the flow meter comprises a drain port in fluid communication with the transducer port. The drain port is axially positioned between the open end and the closed end of the transducer port. Still further, the flow meter comprises a drain conduit having an inlet end coupled to the drain port and an outlet end opposite the inlet end. The drain port is configured to drain a liquid from the transducer port into the inlet end of the drain conduit. | 03-22-2012 |
20120247225 | ULTRASONIC FLOW METER HAVING CABLE SHROUD - A flow meter is disclosed having a meter body that is enveloped by a compliant shroud that protects transducers and transducer cables. The shroud forms a chamber between the shroud and meter body, and includes a releasable portion to allow access into the chamber. | 10-04-2012 |
20130180340 | Meter Having Banded Shroud - A flow meter is disclosed having a meter body that is enveloped by a shroud having a compliant band disposed at least partially about the meter body. The shroud protects transducers and transducer cables. The shroud forms a chamber between the shroud and meter body, and includes a releasable portion to allow access into the chamber. | 07-18-2013 |
20150082880 | Transducer Cable Assembly and Flow Meter Employing Same - A cable assembly for coupling a transducer includes a plug body having a nose section with a nose end, a tail section with a tail end opposite the nose end; and a cable restraining feature disposed proximal the tail end. In addition, the cable assembly includes a cable having a first end, a second end, a signal conductor, and a pliable fixing member. A portion of the pliable fixing member is disposed in the cable restraining feature and extends at least partially around the plug body to limit the movement of the first end of the cable relative to the plug body. | 03-26-2015 |
