NOVELTY - Biogas plant comprises at least two interconnected containers for a gas transfer through gas lines, comprising gas reservoirs, and whose filling level is determined by detection devices and delivered to a regulating device; and a control device for continuously calculating all filling levels and updating an average value, which serves as a target value for the filling levels. The control device control signals of the biogas plant for operating compressors, fans, dampers or valves, and to cause a controlled gas transfer between the gas reservoirs.    USE - Used as a biogas plant.    ADVANTAGE - The biogas plant achieves variable gas consumption and attains improved gas management.    DETAILED DESCRIPTION - Biogas plant comprises at least two interconnected containers for a gas transfer through gas lines, comprising gas reservoirs, and whose filling level is determined by detection devices and delivered to a regulating device; and a control device for continuously calculating all filling levels and updating an average value, which serves as a target value for the filling levels. The control device control signals of the biogas plant for operating compressors, fans, dampers or valves, and to cause a controlled gas transfer between the gas reservoirs. The signals for driving the compressor, blower, flaps or valves are dimensioned such that an equalization of the filling levels is carried out to the desired value. An INDEPENDENT CLAIM is also included for operating a biogas plant comprising measuring the levels in the gas reservoirs and feeding the level readings to a control device, constantly updating a calculated average level of the level reading as a reference for all levels by the control device, and calculating and generating control signals by control device for driving compressors, blowers, flaps or valves such that the filling levels of the individual gas reservoir is adjusted by gas transfer between the gas reservoirs on reaching the target value.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of the biogas plant.
