Intercomparison and method for uncertainty calculation of water and heat flow (NT TR 610)

NT TR 610

  • A relatively high utilisation of district heating and limited resources of drinking water makes metering of water and heat of great importance in both the Nordic and the Baltic countries. This has further resulted in a heavy focus on testing and calibration of the meters as well as on the uncertainty of the meter installation.
