This European Standard specifies the constructional requirements and applies to heat meters, that is to instruments intended for measuring the heat which, in a heatexchange circuit, is absorbed (cooling) or given up (heating) by a liquid called the heatconveying 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. This standard covers meters for closed systems only, where the differential pressure over the thermal load is
limited.
