Abstract

A device for arresting and/or launching a discrete body 1 at the end of a pipeline 2 forming e.g. a flowmeter prover in which the body forms a sliding seal and through which the body is carried by fluid flow comprises a length of pipe 4 continuous with and opening into the pipeline, and having a closed end 6 remote from the pipeline, the internal cross-section of said length of pipe being substantially the same as that of the pipeline; a casing 5 forming a chamber 8 on the exterior of the said length of pipe; an external connection 9 for fluid flow to or from the chamber; and at least one aperture 10 through which the chamber and the interior of the said length of pipe communicate. The apertures are elongate and arranged to form 1 or 2 sets. <IMAGE>
