Thermal energy meters - Part 1: General requirements

This European Standard specifies the general 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.
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.

Compteurs d'énergie thermique - Partie 1 : Prescriptions générales

La présente Norme européenne spécifie les prescriptions générales relatives aux compteurs d'énergie
thermique. Les compteurs d'énergie thermique sont des instruments destinés à mesurer l'énergie
thermique qui, dans un circuit d'échange thermique, est absorbée (refroidissement) ou cédée
(chauffage) par un liquide appelé « liquide caloporteur ». Le compteur d'énergie thermique fournit la
quantité d'énergie thermique en unités de mesure légales.
La présente Norme européenne ne traite pas des prescriptions de sécurité électrique.
La présente Norme européenne ne traite pas des prescriptions de sécurité relative à la pression.
La présente Norme européenne ne traite pas des sondes de température montées en surface.
La présente norme couvre les compteurs pour les systèmes fermés uniquement, où la pression
différentielle dans la charge thermique est limitée.

Merilniki toplote - 1. del: Splošne zahteve (vključno z dopolnilom A1)

Ta evropski standard določa splošne zahteve za merilnike toplote. Merilniki toplote so instrumenti, namenjeni merjenju energije, ki jo v krogotoku toplotne izmenjave absorbira (hlajenje) ali oddaja (ogrevanje) tekočina, imenovana tekočina za prenos toplote. Merilnik toplote podaja toploto v predpisanih enotah.
Ta evropski standard ne zajema električnih varnostnih zahtev.
Ta evropski standard ne zajema tlačnih varnostnih zahtev.
Ta evropski standard ne zajema površinsko nameščenih senzorjev temperature.
Ta standard zajema samo števce za zaprte sisteme, kjer je diferencialni tlak nad toplotno obremenitvijo omejen.
