Abstract
A measuring apparatus (10) for determining the volume flow of glue in a gluing device (100) for an apparatus, particularly a bottoming device or a tubing machine, for manufacturing bags or semifinished bag products. The measuring apparatus (10) comprises a pressure accumulator (20) having a gas volume (22) and a glue volume (24) that is separated from the gas volume (22) by a pressure equalization element (26), particularly a flexible membrane, wherein the glue volume (24) as a glue port (28) for connection to a glue line (110) of the gluing device (100), and the pressure accumulator (20) comprises a pressure sensor (30) for determining the internal pressure inside the pressure accumulator (20).
