Boiler drum level is a critical measurement necessary to maintain efficient, reliable, and safe operations. If the boiler steam/water interface level is too low, it can lead to boiler tube damage due to overheating. This would mean significant cost and downtime in order to make the necessary repairs as well as possible safety risks.

The Industrial Boiler Drum Level control loop is to maintain the drum level within the prescribed limit. Simplyregulating the Boiler Feed Water Control Valve regulates the boiler drum level. The drum level is measured byusing level transmitter. The level signal is compared with fixed set value of level controller. Whenever there is asudden rise in the steam flow the drum pressure decreases. Due to decrease in the pressure there is a temporaryrise in the drum level. …
