Abstract: A multichannel metering system, for metering preselected fluid flows from individual fluid flow sources, includes a control device, and data fields which are located in the control device (memory) and describe at least the metering of the individual fluid flows, and can be polled to an operating surface connected to the control device with a data input circuit and with a data output circuit. The data field associated with a fluid flow source can be selected in a simple manner using selector switches associated as part of the data input circuit with individual fluid flow sources by which selector switches at least segments of the fluid flow source belonging to the fluid flow source selected can be represented on the operating surface. At least part of the data input circuit are switched into functional connection with the data field belonging to the fluid flow source selected.
