In horizontal shell boilers the water level rises with increasing load due to the presence of more steam being below the water level in the boiler.
Water level indicator in boiler wikipedia.
In the case of a boiler the pressure of the water below and the steam above is equal so any change in the water level will be seen in the gauge.
A water level indicator consists of a metal and a strong glass tube with marking the upper and lower ends of these tubes are connected to two gunmetal hollow pipes.
Its accessories include a safety valve water level indicator and level controller.
Level sensors detect the level of liquids and other fluids and fluidized solids including slurries granular materials and powders that exhibit an upper free surface substances that flow become essentially horizontal in their containers or other physical boundaries because of gravity whereas most bulk solids pile at an angle of repose to a peak.
The substance to be measured can be inside a.

Feed water of boiler is also fed to the steam drum through a feed pipe extending inside the drum along the length of the steam drum.
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.
