Dosing apparatus

A method for metering and supplying media via fluid lines to a plurality of target devices, comprising the steps of:

• a) providing a metering device comprising an entry disc having a plurality of entry-side connections and comprising an actuator that is displaceable relative to the entry disc and which comprises a plurality of through-channels, wherein a pump is arranged downstream of each through-channel;
• b) connecting the entry-side connections to containers that are filled with media;
• c) connecting each through-channel to a target device;
• d) transmitting a request for a particular amount of a medium from a first target device to a controller of the metering device;
• e) displacing the actuator relative to the entry disc so that a first of the through-channels associated with the first target device is brought into communicative connection with the connection at which the requested medium is present;
• f) activating the pump, which is associated with the first through-channel, for feeding the requested medium from the container to the first target device.
