Devices and methods for control flow of formation fluids respect to one or more selected parameter relating to the wellbore fluid. In one embodiment, a flow control device for controlling fluid flow into the production tubular uses a flow restriction member that is actuated by a character change of the formation fluid, such as liquid to gas or oil to water. The flow restriction member can be sensitive to a change in density of the formation fluid. The flow restriction member is passive, self-regulating and does not need any power source or control signal to control fluid flow. In one embodiment, the flow control device automatically rotates into a predetermined orientation upon being positioned in the wellbore. A seal disposed on the flow control devices expands into sealing engagement with an enclosure after the flow control device assumed the desired predetermined position.
