  • the invention further relates to a method for dosing a medium arranged in an exchangeable container of a dosing system, which is supplied to a dosing container controlled by a dosing control via a dosing valve connected to the container.
  • Dosing systems can have exchangeable system components, such as containers (eg bags) with a medium to be metered and valves to be connected to the containers.
  • containers eg bags
  • valves to be connected to the containers.
  • Such dosing systems are used for mixing paints, fragrances, foods, pharmaceutical and biotechnological products.

Both the container and the metering valve have a readable by a communication unit coding for identification. In this case, at least one feature feature or state feature in the control unit or in a separate arithmetic unit with at least one threshold and possibly the dosing be interrupted.
  • the disadvantage here is that in the known system, the metering amount and time or the volume to be metered is determined and controlled relatively complex about to be determined flow parameters. Another disadvantage is that in a plurality of interchangeable system components whose codes are read out via a common read connection to the communication unit, which can lead to errors.

Each of the disposable bags is followed by its own metering valve. The Dosing valves and the pump are controlled by a dosing control.
  • the disadvantage here is that it can not be ensured that when replacing a disposable bag each of the correct and intended container is connected.
