An apparatus for volumetric metering of large variable batches of pourable material is disclosed comprising a single chamber of gas-permeable material having a charging port. The chamber is provided in a pivotable gas-tight container, and is connected to a pneumatic system. The container has a position enabling the filing of the metering chamber through the charge port. Positioning of the chamber opening opposite an opening in the housing provides access for insertion and removal of space filling bodies to vary the volume of batches being metered.
