Abstract
A method and device for the determination of the mass and/or the mass proportion of a wall section of a plastic bottle, in particular a section in the vicinity of the bottle shoulder and/or of the bottle neck, where, due to the fact that a relative mass distribution of the side wall is calculated from a distribution of the light transmission through the side wall of the bottle, the mass proportion of the wall section to be determined of the mass of the side wall can be determined with slight error based on the mass distribution even without calculation of the absolute mass values.
