Which device can be utilized to determine water level in a boiler?

The device used to determine the water level in a boiler is the try cocks. Try cocks are small valves installed at various levels on the boiler shell. By opening these valves, an operator can visually check the water level. If water is present, it will flow out of the valve, indicating the water level in the boiler. This is an important safety feature, as maintaining the correct water level is crucial for the safe and efficient operation of a boiler.

In contrast, pressure gauges measure the pressure inside the boiler but do not provide information about the water level. Flow meters measure the flow rate of water through a system, which is unrelated to the level of water within the boiler itself. Safety valves are designed to release excess pressure from the boiler to prevent explosions or damage; they do not indicate water level. Thus, try cocks are specifically designed for monitoring water levels and play a vital role in boiler operation.
