The invention relates to a fermenter for biogas plants, comprising a submersible motor-driven stirrer (6) that can be vertically adjusted by means of a motor. During operation of the biogas plant, the fermenter (1) is filled, to a level (H1), with substrate (3) that is to be fermented, and the agitator blades (7) of the submersible motor-driven stirrer (6) are fully immersed in the substrate (3). According to the invention, a level gauge (15) is provided, by means of which the level (H1) of the substrate (3) is detected and a corresponding level measuring signal (FM) is generated as an actual level signal. Furthermore, a control device (SG) is provided, to which the level measuring signal (FM) is fed and which controls the vertically adjusting motor (14) for the submersible motor-driven stirrer (6) in such a way when a lower level (H1') is detected that the stirrer (6) is lowered and the agitator blades (7) continue to be fully immersed in the substrate.
