(Steam boiler With glass tube) (Hot water boiler with out glass tube most have a pump on the pipework) Some boilers have a coil in them that the water for your faucets that gets heated up from the boiler water but the water is separated from the heating boiler water.
The water level in a steam boiler should never go below half-way in the sight glass. Dirty sight glasses should be cleaned. Additionally, they should be checked to ensure that they are not plugged with crud of some sort. A regular visual inspection of the sight glass is good practice, especially in the heating season. Automatic water feeder.

7. When the water connection between boiler and gauge glass becomes plugged, the water level in the glass will show a level after a while that is: a. Higher than the level in the boiler b. Lower than the level in the boiler c. The same as the level in the boiler d. The gauge is fully filled e. Lower than the bottom of the sight glass.
Steam boiler sight glass: this article describes how to find & use the sight glass (or sight gauge) on a steam heating boiler to check or set steam boiler water level. We explain where the sight glass will be found, how to read its water level, and the relationship between the sight glass reading and the procedure for adding make-up water to
I've never touched those knobs and am not sure how they should be set, but right now they are closed tight and letting water into the boiler with the correct valve does not change the level in the sight glass. I put enough water in to make the warning light go out but then stopped since I wasn't sure what to do next.

It is a glass tube about ⅝" in diameter and about 8-10" high. A good rule of thumb is to see the water level about halfway up the gauge glass.
This water gauge valve set is used with sight glass; the device allows the liquid level in a vessel to be visually inspected. Water gauges are required by the ASME Boiler and Pressure Code on steam boilers, and are also useful in many other applications.
Conductivity probe instruments such as Hydrastep were originally developed as an alternative to sight glasses for steam drums, also known as boiler drums or feed drums. The drawbacks of sight glasses Sight glasses are vertical columns attached to the drum with a glass window for level indication.
Recently i have noticed that when the boiler starts, after few minutes, the water level in the sight glass goes very low that i cannot see any water. At that time my low pressure guage shows me a pressure of a little above 1 PSI.

You should become familiar with the normal level in your sight glass. The next way to prevent low water, is with low water cutoffs (LWCOs).

Water Level Sight Glass — Provides for constant visual observation of the water level in the boiler. Steam Pressure Gauge with a range to 600 psig provided for visual indication of steam pressure. Drain and Blow Down Valves — Facilitate cleaning the boiler during blow down sequence.
If the water level has not yet dropped completely out the sight glass, water may be put into the boiler. If water drops completely out of sight glass, check another sight glass, if both disappear water; do not add water until the boiler is cool enough to prevent any possible damage due to the rapid cooling of the overheated plate.
Jerguson ® Transparent Level Gages are selected for interface level indication, dirty service or any application that requires the use of a shield to protect the glass from corrosion. A transparent gage is also known as a "thru-vision" gage since the gage is constructed with two pieces of flat polished glass assembled on opposite sides of the level gage chamber.
steam boiler water level sight glass During the instant cooling process, the glass exterior is solidified due to rapid cooling while the interior of glass is cooled down relatively slowly. This process will improve the glass exterior compressive stress and interior tensile stress resistance which can improve the overall mechanical strength of
This video shows how to remove the boiler site-glass and clean/change it. Its very easy. All you need is a pair of pliers or proper size wrench. Towels, lubricant, possibly some sand paper.
Just as in the gage glass example, the visible range (4-6) for magnetic level gages must be at least 2 inches above level A and cannot intersect with the steam (1) or water (2) connections
This forces water up the sight glass and displaces the bubble. You might have to do it a couple of times during a run, but better that than the false security of thinking your water level is higher than it actually is.
The level of liquid in the sight glass will be the same as the level of liquid in the tank. Today, however, sophisticated float switches have replaced sight glasses in many such applications. Steam boilers. If the liquid is hazardous or under pressure, more sophisticated arrangements must be made. In the case of a boiler, the pressure of the
A level indicator, whether it be a gage glass, indirect sensing method, or independent remote, is used on a steam boiler to provide a water level reading. A gage glass is the most common form of level indicator found on steam boilers.
Sight glass water bouncing and surging indicates a problem, it's not normal. Clean boiler water in the sight glass will rise and fall slowly. Not bouncing and surging, bubbling and frothing. Too much oil, rust and debris in the water will cause the water not to turn to steam. It's why you need the water clean.
