Heat meters - Part 6: Installation, commissioning, operational monitoring and maintenance
This European Standard specifies installation, commissioning, operational monitoring and maintenance applicable to heat meters, that is to instruments intended for measur¬ing the heat which, in a heat-exchange circuit, is absorbed or given up by a liquid called the heat-conveying liquid. The heat meter indicates the quantity of heat in legal units.
Electrical safety requirements are not covered by this European Standard.
Pressure safety requirements are not covered by this European Standard.
Surface mounted temperature sensors are not covered by this European Standard.

Heat meter installation A.1 Introduction This annex gives recommendations for the installation of heat meters into the heating system of which they form a component. It includes reference to the quality of the heat conveying liquid and contains recommendations of direct concern to the distributor of heat, the building owner and the final consumer. A.2 Criteria for the selection of a heat meter The type, size, accuracy and environmental class of a heat meter is determined according to the operating and environmental conditions of the installation, taking into account particularly the following: a) pressure of the heat conveying liquid; b) physical and chemical characteristics of the heat conveying liquid; c) acceptable pressure loss across the heat meter; d) accuracy requirements; e) temperature ranges in flow and return limbs to the heating system and the system temperature difference; f) expected maximum and minimum flow rate of the heat conveying liquid; g) required thermal power of the heat
