Abstract

The paper deals with accuracy problems when heat energy consumption in district heating (DH) systems is calculated by measuring the DH water ow rate and its cooling. An investigation on the in uence that sizing of ow meters used has on the accuracy of DH water ow mea- surements in a typical DH subscriber station is presented. Furthermore the consequences of the choice of ow meter size on energy metering accuracy is studied. The goal is to determine rules leading to optimal sizing of the ow meters.
