<p>Improved methods and apparatus are provided for structurally interconnecting an instrument manifold with a differential pressure assembly having a pair of tapered NPT threaded outlet ports each adjoining an exterior body surface. First and second connector flanges are provided each having a through passageway for transmitting a pressure signal from the corresponding NPT outlet port in the differential pressure assembly to an inlet port in an instrument manifold. Each connector flange includes a tapered threaded end, a flange end, and a threaded portion fixed between the threaded end and the flange end. The apparatus also includes first and second stabilizer members, and first and second tensioning nuts for exerting a compressive force on the stabilizer members such that the stabilizer members will transmit substantially all radially-directed forces to the differential pressure assembly. According to the method of the present invention, each connector flange is rotated for obtaining sealing engagement between each connector flange and a respective port in the differential pressure assembly, and the one or more apertures in the flange end are rotated to a preselected rotational position prior to tightening the tension nuts for exerting force on the stablizer members.</p> |
