Removal device (100) for fluids (20), in particular liquids, from a container (10), having an outlet chamber (30) for receiving fluid (20) from a connected container (10) via an inlet opening (28). An outlet pipe (34, 34A) with a valve (46) and / or pump (40) is connected to the outlet chamber (30) via an outlet opening (32). At the outlet chamber (30), a vertically upper end (36) of the outlet opening (32) is arranged lower than a vertically lower end (38) of the inlet opening (28) relative to a horizontal fluid level (20). Based on a determined fill level (58) of fluid (20) in the drain chamber (30), a control unit (42) controls the valve (46) and / or the pump (40) in such a way that the fill level does not fall below a minimum and thus a Entry of air into the outlet pipe (34, 34A) is prevented.
