Drum level measurement in power plant
WebBoiler Drum Level Control Systems. Drum Level Control Systems are used extensively throughout the process industries and the Utilities to control the level of boiling water contained in boiler drums on process plant and … WebControlling the level is critical because if the level is too low, the drum heats dry and damages the mechanical components. And if the level is too high, the water can get into the steam pipe, possibly damaging the downstream equipment. Hence in level measurement two levels are measured an upper and bottom level are measured.
