1. An apparatus for conveying viscous material out of a barrel-like container that has a container bottom and a container mantle that extends upward from the container bottom, the apparatus comprising:
a follower plate that can be moved in the direction toward the container bottom and away from the container bottom, lying against the inner surface of the container mantle, which faces the container interior, and that has a material outlet opening and at least one de-aeration opening and/or at least one aeration opening,
a de-aeration device for drawing off air from the container interior through the de-aeration opening(s) and/or an aeration device for introducing compressed air into the container interior through the aeration opening(s),
a lifting and lowering device for lifting and lowering the follower plate,
a control device for alternately controlling the lifting and lowering device in a movement mode and the de-aeration device or the aeration device in a de-aeration mode or in an aeration mode,
wherein the lifting and lowering device has at least one holding rod that runs vertically, which is connected with a top side of the follower plate and extends downward from a support element that can move in the vertical direction,
wherein the follower plate can be moved vertically, within limits, with reference to the at least one holding rod and/or with reference to the support element, and
a sensor device for detecting at least one upper end position and at least one lower end position of the follower plate with reference to the at least one holding rod or with reference to the support element and for transmitting the detected positions to the control device.
