1. A method for regulating a conveying system for fluid media with several parallel conveying lines (11) with the proviso of a constant total conveyed flow, the conveying lines (11) being supplied from a single conveying unit (9), wherein the constant conveyed total flow is divided in the respective conveying lines (11) into specified sub-flows by regulating sub-flow resistances (1), which are ascertained continuously as a ratio of a total pressure value to a sub-flow value, in that the ascertained ratios, as actual values, are compared with a specified value for each conveying line (11) and, depending on the magnitude of the respective deviation between the actual value and the specified value, a regulation of the respective sub-flow resistance (1) and, with that, of the sub-flow of the fluid medium in the respective conveying line, takes place.
