ABSTRACT:
The invention relates to a method of determining the filling capacity of a pneumatic conveying arrangement by three pressure measurements. The invention also relates to a method of calibrating a pneumatic conveying arrangement using this determination of the filling capacity. These measurements are conveying pressure, pressure at the top of the vessel from which the material is conveyed, and pressure at the top of the vessel to which the material is conveyed.
