To monitor water levels

The primary function of a low-water cut-off device is to monitor water levels. This device plays a crucial role in boiler safety by detecting the water level within the boiler. When the water level falls below a predetermined threshold, the low-water cut-off activates to shut down the burner or the boiler itself, preventing damage that can occur from insufficient water levels, such as overheating or a potentially hazardous condition. Without this device, a boiler could operate without adequate water, leading to overheating of the boiler components, which could result in serious accidents or failures. Therefore, monitoring water levels is essential for ensuring safe and efficient operation of the boiler system.
