Abstract
A fluid transportation network (1) comprises a plurality of parallel zones (Z1, Z2), fed by a common supply line (L), with a regulating zone valve (V1, V2) in each zone (Z1, Z2) for regulating a flow of fluid (ϕ1, ϕ2) through the respective zone (Z1, Z2). A processing unit (RE) receives valve positions (pos1, pos2) of the regulating zone valves (V1, V2) and determines and sets an adjusted valve position for a line valve (VE) arranged in the supply line (L), depending on the valve positions (pos1, pos2) of the regulating zone valves (V1, V2). A processing unit (RE) further receives a measurement of a total flow of fluid (ϕtot) through the supply line (L) and determines and sets adjusted valve positions for the regulating zone valves (V1, V2), depending on the measurement of the total flow of fluid (ϕtot) through the supply line (L).
