1. A flow control device comprising:

  • a flow measuring device configured to generate a flow feedback signal indicative of a volume of content flowing within a line of a dispensing system;

    a feedback controller system, responsive to the flow feedback signal and configured to compare a desired flow volume to the flow feedback signal to generate a flow control signal, wherein the feedback controller system includes a feed forward controller for establishing, at least in part, an initial value for the flow control signal; and

    a variable line impedance positioned within the line of the dispensing system and responsive to the flow control signal, the variable line impedance being configured to regulate the volume of content flowing within the line of the dispensing system based, at least in part, upon the flow control signal.
