Apparatus and methods for controlling the flow of fluid, such as formation fluid, through an oilfield tubular positioned in a wellbore (12) extending through a subterranean formation. Fluid flow is autonomously controlled in response to change in a fluid flow characteristic, such as density. A fluid diverter (101, 301) is movable between an open and closed position in response to fluid density change and operable to restrict fluid flow through a valve assembly inlet (204, 206, 404, 830, 832). The diverter can be pivotable, rotatable or otherwise movable in response to the fluid density change. The diverter can control a fluid flow ratio through two valve inlets. The fluid flow ratio is used to operate a valve member (720, 822) to restrict fluid flow through the valve. The fluid diverter can move in response to density change in the fluid to affect fluid flow patterns in a tubular, the change in flow pattern operating a valve assembly.
