The present disclosure sets forths a pipeline insertion mechanism. It cooperates with the pipeline having a tee, blocking valve and stuffing box. An elongate insertion rod is extended from the exterior through the stuffing box, blocking valve and tee so that a measuring instrument is positioned at a centerline location in the pipeline. This rod connects to a transverse yoke having two ends which connects at the remote ends to piston rods. Two piston rods cooperative with two hydraulically cylinders are positioned adjacent to the blocking valve and stuffing block to reduce height of the equipment. The insertion rod is moved axially to insert or retract the measuring instrument.

[ What is claimed is:] [1.] A method of inserting a measuring instrument into the central portions of a pipeline to thereby measure aspects of fluid flow through the pipeline, and including the steps of:(a) positioning a measuring instrument on an end of an insertion rod;(b) positioning the insertion rod through a stuffing assembly so that the end thereof is moveable into or away from the interior of the pipeline;(c) applying a force to a second end of said rod wherein the second end is on the exterior of the pipeline so that the second end is forced toward the pipeline to achieve insertion into the pipeline;(d) utilizing line pressure to form a pressurized fluid applied to a motive means to thereby force movement of said rod; and(e) wherein the step of applying a force to the second end of said rod is accomplished laterally of said rod which precludes extending beyond said rod.
