In pneumatic testing and inspection procedures, the changes in pressure at the measuring point are used to determine spacings, weights and changes in shape. This allows passing articles to be counted, correct positioning to be checked and the presence of workpieces to be ascertained.

This process is an integral part of many sorting, positioning and processing systems.
