Abstract
A method for calculating the height and the density of a fluidized bed is described. In a first mode of operation, a first differential pressure and a second differential pressure are obtained, a bed density of the fluidized bed is calculated, and a bed height is calculated by dividing the first differential pressure by the calculated bed density. In a second mode of operation the system is purged by using a pressurized gas.
