ABSTRACT:
Apparatus and method for measuring the amount of lean present in a glass container. A glass container is mounted for rotation about its vertical axis. A pivotally mounted follower member is positioned to be in contact with the upper portion of the container. A fluidic position transmitter is mounted behind the follower and directs a stream of air from a nozzle against the rear face of the follower. The position transmitter will keep a constant gap between its nozzle and the follower by moving the nozzle. As the glass container is rotated, the follower will move in response to any deviation of the top portion thereof from a true vertical axis. The position transmitter will generate a back pressure signal in response to movement of its nozzle to maintain a constant spacing from the moving follower. This back pressure signal may then be processed to obtain a measure, in dimensional units, of the deviation of the top portion of the container from a true vertical axis.
