  • a successful or completed dosing process can be determined by the dosing device, for example, if the dosing device was able to meet the corresponding requirements of the target device. For example, a successful or successful execution of the dosing process can be tested by the dosing device if the requested medium has been pumped in sufficient quantity, i.e. according to the requested volume, from the pump assigned to the dosing device to the target device.
  • a message from the pump of the metering device can contribute to the determination of a successful metering process.

  • a dosing request is received from a corresponding target device 11a or 11b via the corresponding signal line 25a or 25b
  • a corresponding fluid connection is first established between the relevant container 12a, 12b, 12c and the corresponding delivery line 26a and 26b by responding to the two motors 20a, 20b.
  • the specified delivery rate is delivered in terms of volume to the corresponding target device 11a or 11b.
  • only a single pump 23c can be provided in the area of the intermediate line 35 in a further exemplary embodiment.

  • an importance scale can also be introduced - and used when processing dosing processes - that takes into account, for example, that certain target devices should or may not pause indefinitely, at least at certain times during certain washing or cleaning processes.
  • dosing processes could under certain circumstances be brought forward, this also including the possibility that already started dosing processes are aborted and paused in order to be continued later after a second dosing process has been carried out.
  • the dosing device 10b or the in the control unit 21 integrated device 36 for collision prevention ensure that the target device that has lower priority, for example, has to wait a little, is informed that the dosing process can or will start later, for example a few minutes later .

  • the metering device 10c Fig. 3 For the sake of clarity, in Fig. 3 but only two target devices 11a and 11f are shown.
  • the dosing device 10c can also control or prevent a collision of simultaneous dosing requests from different target devices 11a, 11f via the communication interface 22 by means of the collision avoidance device 36 integrated in the control unit 21.
  • Fig. 3 shows a cascade of mixing distribution devices 34a, 34b, 34c with the result that a large number of target devices 11a, 11b can be charged with one medium or with different media by means of a single metering device 10c.
  • Fig. 3 also includes those variants in which a multiplicity of containers, in particular a multiplicity of different media, are connected to the metering device 10.
  • the device 36 for preventing collisions can be an integral part of the corresponding control unit 21 on the metering device 10, or can also be designed separately from it.
  • the device 36 for preventing collisions can be formed by a microprocessor, or it can be a component of the control unit 21 of the metering device 10, 10a, 10b, 10c.
