Abstract: The present invention relates to a metering station (10) which allows liquids with elevated viscosity to be metered, especially liquids with a viscosity which is more than one hundred times the viscosity of water. The metering station is operated partly or fully automatically and has a modular structure. A metering module (1, 1?) comprises at least one plug connecting element (8), with whose aid the metering module (1, 1?) can be made to engage with a corresponding receiving device (9) for the plug connecting element. The plug connecting elements (8) are preferably multifunctional plugs which have at least one fluidic connecting element. In a further preferred embodiment, the plug connecting element (8), in addition to the at least one fluidic connecting element, also has at least one electrical connecting element for process control.
