Pipeline system for the controlled distribution of a flowing medium and method for operating such a pipeline system

A pipeline system (10) for the controlled distribution of a flowing medium comprises a main line (11) which branches at a branching point (12) into a plurality of branch lines (13,14,15), in each of the branch lines a variable restrictor (V1,V2,V3), by means of which the mass flow in each of the branch lines (13,14,15) can be adjusted and, belonging to each restrictor (V1,V2,V3), a first pressure measuring device (PM1,PM2,PM3), by means of which the pressure drop of flowing medium at the respective restrictor (V1,V2,V3) is measured. Redundancy in measurement, at a limited additional outlay, is obtained in that at least between two of the branch lines (13,14, or 13,15 or 14,15) a second pressure measuring device (PM10 or PM11 or PM12) for measuring the differential pressure between the respective branch lines (13,14 or 13,15 or 14,15) is arranged downstream of the restrictors (V1,V2 or V1,V3 or V2,V3) in the direction of flow.
