Abstract
A pipeline apparatus has a body configured to fit inside a pipeline. A flow channel is formed within the body and includes an inlet, an outlet, and a bypass channel connecting the inlet and the outlet, the inlet being configured to receive a portion of a fluid flowing through the pipeline, and the outlet being configured such that the fluid flowing through the bypass channel flows out of the bypass channel through the outlet. A flow control valve is attached to the body and has a sleeve configured to move to vary a flow rate of the fluid flowing out of the outlet. A conduit is connected between the flow control valve and a back face of the body and configured to communicate a high pressure of the fluid to the flow control valve.
