Auxiliary Plant - an overview | ScienceDirect Topics

Most boilers are supplied with a float-operated primary low water cut-off (and pump control or water feeder combination) or electric probe type auxiliary control. These water level controls are intended to sense (and control) the level of the water in the boiler. They operate to shut off the boiler if the water level drops below their sensing level.
