The invention relates to a method and a device for the discontinuous gravimetric dosing of bulk material of a batch C from a storage container (9) into a collection, mixing, or reaction container (21) by means of a dosing scale (1). The dosing scale (1) is pressurized with a process gas (18) during filling from the storage container (9) and dosing into the collection, mixing, or reaction container (21). To ensure high dosing accuracy and simultaneously meet increased containment requirements, the following method steps are carried out with the method and device according to the invention: a) Filling the dosing scale (1) from the storage container (9) up to a
first fill level, b) Carrying out a pressure
equalization between the interior of the dosing scale (1) and the environment of the dosing scale (1), c) Determine a first
weight value G ieof batch C by weighing at the
first fill level in the dosing scale (1), d) generating an
overpressure in the dosing scale (1) compared to the
ambient pressure by feeding a process gas (18) into the dosing scale (1), e) Dosing batch C from the dosing scale (1) into the collection, mixing or reaction container (21). f) Carrying out a pressure
equalization between the interior of the dosing scale (1) and the environment of the dosing scale (1), g) Determining a second
weight value G iz of batch C by weighing, with a second fill level in the dosing scale (1) after dosing has been completed, h) Determine the weight G of batch C by calculating the difference between the weight values G ie and G iz , i) Generating an
overpressure in the dosing scale (1) compared to the
ambient pressure by feeding a process gas into the dosing scale (1).
