Title: ASSEMBLY FOR CONTROL AND/OR MEASUREMENT OF FLUID FLOW
Abstract:
An assembly for the control of the flow of a fluid stream is provided, the assembly comprising a fluid flow conduit having a longitudinal axis; an inlet in the conduit for the fluid stream being processed; an outlet in the conduit for the fluid stream being processed; a control fluid feed assembly having an inlet for a control fluid; wherein the conduit comprises a control portion having one or more apertures therein, the control portion being disposed between the inlet and the outlet of the conduit, the one or more apertures being in flow communication with the inlet for the control fluid in the flow control assembly and extending in a direction at an angle to the longitudinal axis of the fluid flow conduit; whereby in use the control fluid supplied to the inlet of the control fluid assembly is caused to flow into the conduit through the one or more apertures. A method for the control of the flow of a fluid stream comprises causing the fluid stream to flow through a flow control zone from an inlet to an outlet in a first direction; introducing a flow of a control fluid into the flow control zone through one or more apertures at a pressure above the pressure of the fluid stream, whereby the control fluid flows into the fluid control zone at an angle to the first direction to thereby cause a restriction to the flow of the fluid stream through the flow control zone in the first direction.
