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. Normally two water level indicators are fitted at the front end of every boiler. Water level indication applies to steam boilers where the water level can be detected.

A lot of rules determine to use and arrange two gauge glasses especially for steam boiler which has maximum allowable working pressure above 400 psi or above 28 bar to reduce possibility of breakage which can cause the operator in danger. It includesmost steam boilers the exception being those of the once through or coil type where there is no steam drum. The steam cock connect or disconnects the glass tube with steam space.
