The system for controlling flow characteristics allows a user to selectively modify the inherent fluid flow characteristics of a fluid transmission system including a flow process controller and a control valve positioner. The system includes a programmable flow controller having an input adapted for receiving an input signal from the flow process controller. The programmable flow controller selectively modifies the input signals generated by the flow process controller depending upon user-selectable flow parameters. An output is in communication with the programmable flow controller, with the output being adapted for transmitting output signals to the control valve positioner (and the valve connected thereto). A user interface is provided for inputting the user-selectable flow parameters to the programmable flow controller for modification of the input signal to the user-selectable flow parameters.
