Special challenges
Strong fluctuations of density, conductivity and dielectric constant of the hot water
Application
In the heat recovery boiler, hot process gas is passed through heating pipes. This means the gas is cooled and the necessary process heat for the plant recovered to be reused. To prevent the heat recovery boiler from running dry and thus overheating, reliable monitoring of the water level in the boiler is required. For maximum safety, the measurement is carried out redundantly with diverse instrument technology.
