Abstract: Online installation systems and methods are provided for online installations of ultrasonic steam measurement devices in steam pipes. In one embodiment, a tool is provided and includes a transducer assembly configured to be coupled to a distal end of an isolation valve installed on a pressurized steam pipe. An ultrasonic transducer can be movably disposed within the transducer assembly, and the ultrasonic transducer can extend through a proximal opening of the transducer assembly and through a distal opening of the transducer assembly. The tool can also include an insertion mechanism configured to be coupled to a distal end of the transducer assembly and having a cylindrical housing at least partially enclosing the ultrasonic transducer. The insertion mechanism can include a linear actuator assembly configured to linearly actuate the ultrasonic transducer.

Abstract: An electrical feed through assembly includes a mechanical connector extending between a first end and a second end. The mechanical connector defines at least one opening through the mechanical connector between the first end and the second end. The electrical feed through assembly includes a first electrical connector attached to the first end of the mechanical connector. The first electrical connector includes a conductor portion that extends through the at least one opening in the mechanical connector. The first electrical connector includes a grounded portion within which the conductor portion is received. An inner radial surface of the grounded portion is sealed with the conductor portion. An outer radial surface of the grounded portion is attached to the mechanical connector.
