Abstract: Adjustable passive choke devices, systems, and methods for controlling fluid flow rate, pressure, or both, are provided. The adjustable passive choke devices may comprise a fluid conduit having a first end, a second end, and an intervening portion therebetween, the intervening portion comprising a flow resistance element for reducing a flow rate of a fluid when the fluid is passed through the fluid conduit from the first end to the second end. The devices may further comprise a selectable bypass line connected upstream and downstream of the flow resistance element, or a portion thereof, operable to provide a fluid flow bypass path bypassing all, or a portion, of the flow resistance element when activated.

Abstract: Adjustable passive choke devices, systems, and methods for controlling fluid flow rate, pressure, or both, are provided. The adjustable passive choke devices may include a fluid conduit having a first end, a second end, and an intervening portion positioned in between the first and second ends, the intervening portion having a flow resistance element for reducing a flow rate of a fluid when the fluid is passed through the fluid conduit from the first end to the second end. The devices may also include a selectable bypass line, which is connected upstream and downstream of the flow resistance element and provides a fluid flow bypass path bypassing at least a portion of the flow resistance element when activated.
