Abstract

For the purpose of balancing (S3) a group of consumers in a fluid transport system in which each consumer is configured with a motorized regulating valve for the purpose of regulating the flow through the consumer, characteristic data for the consumer is saved (S2) which determines a valve position of the corresponding regulating valve for the target throughput through each consumer. A momentary total throughput through the group of consumers is determined (S32) by means of a common throughput sensor, and based on the momentary total throughput and a sum of the desired target throughputs through the consumers, a balancing factor is determined (S34). By setting (S31) the valve positions of the corresponding regulating valves based on the characteristic data and the balancing factor, a dynamic balancing of the consumers is carried out.
