Abstract
The present disclosure describes a fuel system for an engine. The fuel system includes a fuel metering valve, a flow measuring system, and a controller in communication with the fuel metering valve and the flow measuring system. The fuel metering valve is operable to meter a flow rate of fuel based on a stroke of the fuel metering valve. The flow measuring system is configured to measure a mass flow rate of the fuel leaving the fuel system at a bandwidth greater than 20 Hz. The controller is configured to dynamically adjust the stroke of the fuel measuring system based on the mass flow rate of the fuel measured by the flow measuring system to change the flow rate of the fuel.
