Uncertainty calculations for calibration of water and heat flow meters (NT VVS 131)

NT VVS 131

  • The aim of this method is to provide a basis for uncertainty calculations for testing/calibrating/verifying the flow measurement part of water and heat meters. The method is designed for being used as a guideline in combination with existing standards for flow measurement and uncertainty calculations.

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.
