Flow control method, system and apparatus

Presented is a method, system and apparatus for fuel flow control. An exemplary fuel flow control apparatus includes a fuel inlet operable to receive a flow, and a fuel shut-off valve fluidly connected to receive the flow from the fuel inlet, the fuel shut-off valve is operable to allow the flow in a first configuration and prevent the flow in a second configuration. The apparatus further includes a pressure regulator fluidly connected to receive the flow from the fuel shut-off valve, a flow control valve fluidly connected to receive the flow from the pressure regulator, the flow control valve comprising a position sensor operable to sense a position of the flow control valve, an injector fluidly connected in parallel to the flow control valve to receive the flow from the pressure regulator, and a fuel outlet.
