Thermal energy meters - Part 6: Installation, commissioning, operational monitoring and maintenance
This European Standard specifies commissioning, operational monitoring and maintenance and applies to 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.
Thermische Energiemessgeräte - Teil 6: Einbau, Inbetriebnahme, Überwachung und Wartung
Diese Europäische Norm gilt für !thermische Energiemessgeräte" und legt die Inbetriebnahme, die Überwachung und die Wartung von diesen fest. !Thermische Energiemessgeräte" sind Geräte, die dazu dienen, die Energiemenge zu messen, die in einem Wärmeübertragerkreislauf durch eine als Wärmeträgerflüssigkeit bezeichnete Flüssigkeit aufgenommen (Kühlen) oder abgegeben (Heizen) wird. Das !thermische Energiemessgerät" zeigt die Wärmemenge in gesetzlichen Einheiten an.
Elektrische Sicherheitsanforderungen werden in dieser Europäischen Norm nicht behandelt.
Den Druck betreffende Sicherheitsanforderungen werden in dieser Europäischen Norm nicht behandelt.
Oberflächenmontierte Temperaturfühler werden in dieser Europäischen Norm nicht behandelt.
Die vorliegende Norm behandelt ausschließlich Zähler für geschlossene Systeme, in denen der Differenz-druck über die Wärmemenge begrenzt ist.
Compteurs d'énergie thermique - Partie 6 : Installation, mise en service, surveillance et maintenance
La présente Norme européenne spécifie l'installation, la mise en service, à la surveillance de fonctionnement et la maintenance et s'applique 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 - 6. del: Vgradnja, zagon, nadzor in vzdrževanje (vključno z dopolnilom A1)
Ta evropski standard določa zagon, nadzor delovanja in vzdrževanje ter se uporablja za merilnike toplotne energije. 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.

The values below the marked line are higher than 1/3rd of the maximum permissible error for the heat calculator. If the resulting error is higher than 1/3rd of the maximum permissible error, it is recommended to change the installation to have smaller differential pressure. NOTE In cases where flows from two different loads with different temperatures (e.g. for space heating and domestic warm water) are merged together just before the temperature sensor, the optimum position for the sensor is after the flow sensor.
