ABSTRACT:
A tubular body for reducing the rate at which a fluid flows to a predetermined rate with a resistance in a flow control device of a pressure measuring system, includes a tubular member having an axis along which the fluid can flow therethrough, and a land projecting radially inwardly from an inner wall surface of the tubular member. The tubular member and the land are integrally formed as a unitary structure, the land having an orifice extending along the axis of the tubular member. A method of manufacturing the tubular body, and a flow control device incorporating the tubular body are also disclosed.
