4 key measurements for optimal boiler control Flow

Drum level measurement is not as simple as it might appear. Typical challenges include the need for high-pressure and high-temperature equipment, the fact that density and dielectric (DC) of water and steam vary as pressure and temperature change, and that the control ranges across a small span. Another issue is the shrink and swell phenomenon.
