What is the function of a low water cutoff device in a boiler system?

The function of a low water cutoff device in a boiler system is to enhance safety by shutting down the boiler if the water level falls below a safe threshold. This is crucial because if the water level drops too low, it can lead to overheating, equipment damage, or even catastrophic failure due to the boiler overheating without water to absorb the heat. The low water cutoff ensures that the boiler operates within a safe water level range and protects the system from the problems associated with low water conditions.

In terms of function, this device detects the level of water in the boiler and initiates a shutdown automatically if it senses a drop to a level that could be dangerous. This action is critical in maintaining safe operating conditions and preventing accidents.
