This European Standard specifies the constructional requirements for thermal energy meters. Thermal energy meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The thermal energy meter indicates the quantity of heat in legal units.<\/p>\n

Electrical safety requirements are not covered by this European Standard.<\/p>\n

Pressure safety requirements are not covered by this European Standard.<\/p>\n

Surface mounted temperature sensors are not covered by this European Standard.<\/p>\n

This standard covers meters for closed systems only, where the differential pressure over the thermal load is limited.<\/p>\n
