Bibliography
This European Standard specifies pattern approval tests and applies to heat meters. Heat 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 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.
