Beschreibung
Zusammenfassung:	A conveying device for conveying a viscous material from a container includes a follower plate that can be inserted into the container, and a pump by means of which the viscous material can be conveyed through the follower plate. Moreover, a measuring chamber for accommodation of a measuring sample of the viscous material is provided. The measuring chamber includes a closable material inlet opening for this purpose. A closable disposal line leads away from the measuring chamber. Moreover, a closable material return line extends from the measuring chamber via the follower plate into the container. The conveying device also includes a controller that is designed and can be operated appropriately such that it determines the compressibility of each of multiple measuring samples. The controller opens the disposal line or the material return line to the measuring sample present in the measuring chamber as a function of the compressibility thus determined.
