Abstract

To balance (S3) a group of consumers in a fluid transport system in which each consumer is provided with a motorized control valve for regulating the flow through the consumer, characteristic data for the consumers is stored (S2) which determines a valve position of the relevant control valve for target flows through one of the consumers in each case. A current total flow through the group of consumers is determined by means of a common flow sensor (S32) and a balance factor (S34) is defined on the basis of the current total flow and a sum of the desired target flows through the consumers. The consumers are dynamically balanced by setting (S31) the valve settings for the corresponding control valves on the basis of the characteristic data and the balance factor.
