1. For use with a pipeline flowing a fluid therethrough and wherein a pressure differential in the pipeline is created across a differential pressure producing restriction within the pipeline, unitized connector apparatus for connecting measuring instrumentation with the pipeline, the connector apparatus comprising an elongate unitized body having two remote ends and a lengthwise passage between the two ends, said body also being adapted to thread and support serially with said passage first and second spaced valve assemblies for selectively opening and closing for selective valving action of fluid flow along said passage, and wherein said passage terminates at multiple tapped openings on said body at each end to enable connections to be made with said body on installation between openings in a pipeline and the measuring instrumentation for providing two fluid pressure signals from the pipeline through said apparatus to the measuring instrumentation connected thereto, and said body is elongate bar stock having a cross-section and said passage is axially positioned along the length thereof;

  • said bar stock has a pair of opposing parallel side faces perforated with two of said multiple tapped openings formed as opposing tapped openings and the two tapped openings are aligned on opposite faces of said body and are connected directly therethrough to enable rodding through one of said tapped openings and out the opposing opening for cleaning purposes;

    wherein said body is roddable through said lengthwise passage from one end thereof; and

    one of said multiple tapped openings is aligned with said passage to enable a rod to be inserted through said passage at said tapped opening through the full length of said body and out the corresponding multiple tapped opening on the opposite end thereof.
