Abstract
The method according to the invention is suitable for determining a powder quantity in a container and for determining a change in powder quantity, i.e. the powder quantity that is supplied from the container(s). The powder is fluidized in the container, the pressure of the fluidized powder in the container is measured to determine the pressure of the fluidized powder or the change of the pressure between two measurements, wherein the powder quantity in the container, or which was supplied from the container between two measurements is calculated from the pressure or the change in pressure. By the method according to the invention it is possible by a simple pressure measurement to determine the powder quantity which is supplied per time unit from the container and which is sprayed by the coating apparatus, and therefore to determine the supplied powder mass flow.
