In boiler systems, in addition to sight glasses used for monitoring water levels, many plants also incorporate linear control valves to stabilize steam flow and operating temperatures. You can find more information here:

Although a boiler sight glass is a small component, it has a direct impact on the safety of the entire system.
If the sight glass becomes:
cloudy,
cracked,
corroded, or
leaky at the gasket,
it becomes very difficult for operators to accurately monitor the actual water level.
This is a common cause of:
boiler water depletion,
damage (burning) to steam-generating tubes,
production stoppages, and
compromised operational safety.
The MAXOS 250x34x17mm (DIN 7081) sight glass is a popular choice in many industrial plants today.

Practical Insights from Phat Dat
With over 15 years of experience in boiler equipment, we have encountered many such scenarios:
Operators notice a slight crack in the sight glass but continue to run the equipment anyway.
Initially, it may just appear slightly cloudy.
Subsequently, this leads to:
Difficulty in observing the water level.
Misreading the water level.
Incorrect operation.
Boiler dry-firing (running out of water).
This is an extremely dangerous error.
Practical advice:
If the sight glass shows any of the following signs:
Cloudiness (whitening).
Thermal streaks.
Cracks at the base.
Gasket leaks.
Replace it immediately.
Do not wait until the glass shatters.
Practical Applications
Boilers
Monitoring the water level in the steam drum.
Drying systems
Monitoring the heat-transfer fluid (thermal oil).
Coffee roasters
Monitoring the thermal oil.
Food processing tanks
Monitoring the liquid contents.
Pharmaceutical plants
