ABSTRACT:
A meter mounting mechanism which is hydraulically operated is disclosed. It is particularly adapted to insert and position a meter transducer in a high pressure environment. The illustrated embodiment discloses a flange-mounted mechanism for positioning a sensor in a pipeline against extremely high pressures. The apparatus utilizes a flange-mounted, correctly oriented, bottom plate which secures an elongate cylinder. The cylinder encloses a piston on a piston rod. The piston rod extends above and below the cylinder. The piston rod is hollow to permit transducer connections can extend through it. The piston rod carries a transducer at the lower end. The transducer is able to be retracted on the rod into a shield to protect it. The piston rod extends upwardly through the head of the cylinder and on the exterior and further is equipped with a mechanism for locking the rod against rotation so that the rod does not rotate to thereby continue azimuthal orientation of the rod, piston and transducer mounted at the lower end.
