Boiler Automation

In a steam boiler, the water level drops as water turns into steam, and the lost water is replenished by the boiler feedwater pump. Due to changes in steam pressure depending on the amount of steam exiting the boiler, and because the incoming water temperature is lower than the boiler temperature, a constant fluctuation occurs in the water level. For efficient and safe operation of the boiler, the water level must be constantly monitored. Otherwise, quality steam cannot be obtained. Furthermore, serious boiler failures and accidents may occur.
