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 or viscosity. A fluid diverter (101) 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. The diverter can be pivotable, rotatable or otherwise movable in response to the fluid density change. The diverter is operable to control a fluid flow ratio through two valve inlets (204, 206). The fluid flow ratio is used to operate a valve member (212) to restrict fluid flow through the valve.
