Low water and your boiler - Pennsylvania Lumbermens Mutual

The probe type device is typically used in water heating boilers or as a secondary low water protection device on a steam heating boiler. The flow-switch type low water protection device does not actually measure the water level in the boiler. Rather than determine the water level, it measures the amount of water flowing into the boiler.

Methods of Detecting Water Level in Steam Boilers

Low water alarm - For safe boiler operation, the low water alarm ensures that the combustion of fuel does not continue if the water level in the boiler has dropped to, or below a predetermined level. For automatically controlled steam boilers, national standards usually call for two independent low level alarms, to ensure safety.

Notes - Boiler Water Levels - Southern Steam Trains

The trapped air may or may not be vented off by the operator, but at some point, as the temperature of the of the heated water exceeds 212F, steam will begin to be present in the space above the boiler's water level. The boiler's pressure will continue to rise until the pressure relief device opens. At this point locomotive is ready to go!
