Cascade, Feed Forward and Boiler Level Control Control Guru
Apr 9, 2015 The level controller transmits its target flow as a set point to a flow controller . The flow controller then decides how much to open or close the valve as supply pressure swings to meet the set point target. This is a 2-element ( boiler liquid level to feedwater flow rate) cascade control strategy.
