What is an alternative method to verify water level without using the gauge glass?

Using try cocks is a reliable alternative method to verify water level in a boiler without employing gauge glass. Try cocks are small valves that allow operators to check the level of water inside the boiler. By opening these valves at various heights, one can observe the water level by the flow of water that exits the try cock. If water is present at the level of the try cock, it indicates the corresponding water level in the boiler.

This method is particularly useful when the gauge glass is not functioning properly or is obscured, ensuring that operators can maintain a safe and efficient operation of the boiler. Each try cock provides a direct way to check the level without the need for more complex instrumentation. Thus, utilizing try cocks is both practical and effective in ensuring accurate water level readings.
