    Two-element control uses inputs from the boiler water level controls and the steam flowrate to position the feedwater control valve. Three-element control uses the above two elements plus an input from a feedwater flow measuring device to control the incoming feedwater flowrate, rather than just the position of the feedwater control valve.
