  • Patent number: 5396814
    Abstract: A method of hot tapping a pipe for installing a carrier for use with a sonic flowmeter transducer includes the steps of welding an alignment fixture to the pipe, attaching a drilling device to the alignment fixture, drilling a hole in the pipe, removing the drilling device and replacing it with a cleaning assembly to remove metal shavings, replacing the cleaning assembly with an extraction assembly which is used to remove the drilling device, removing the extraction assembly and installing an insertion assembly to which a carrier is removably attached. The insertion assembly is employed to secure the carrier to the alignment fixture. The insertion assembly and the drilling device are then detached from the alignment fixture and are ready for reuse.

  • Patent number: 4969362
    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,
