ABSTRACT:
A fuel control is provided having a metering means for metering a weight flow of fuel, a control for controlling the metering means, a valve for determining a change in fluid pressure of the weight flow of fuel downstream of the metering means, the valve having; a pressure reaction surface disposed in the weight flow downstream of the metering means, the surface controlling an area of a window passing the weight flow of fuel therethrough, a spring attaching to the pressure reaction surface for balancing the change in fluid pressure of the weight flow of fuel against the pressure reaction surface, and a position sensor for continuously determining a position of the pressure reaction surface and continuously sending a signal of the position to the control means, wherein the control means determines the weight flow of fuel through the valve means according to the equation: ##EQU1## whereby K is a constant, F(X) is equal to an area of the window as a function of X, X is equal to a position of the reaction surface which controls the area of the window, Fo is a preload force of the spring, Ks is equal to a spring rate of the spring, and Av equals the area of the reaction surface.
