Gas meters - Turbine gas meters

This document specifies the measuring conditions, requirements and tests for the construction, performance and safety of class 1,0 axial and radial turbine gas meters with mechanical indicating devices, herein after referred to as a meter(s), having in-line pipe connections for gas flow measurement.
This document applies to turbine gas meters used to measure the volume of fuel gases of the 1st and 2nd gas families, the composition of which is specified in EN 437, at maximum working pressures up to 420 bar, actual flow rates up to 25 000 m³/h over a gas temperature range of at least 40 K and for a climatic environmental temperature range of at least 50 K.
This document applies to meters that are installed in locations with vibration and shocks of low significance and in
-   closed locations (indoor or outdoor with protection as specified by the manufacturer) with condensing or with non-condensing humidity
or, if specified by the manufacturer,
-   open locations (outdoor without any covering) with condensing humidity or with non-condensing humidity
and in locations with electromagnetic disturbances.
Unless otherwise specified in this document:
-   all pressures used are gauge;
-   all influence quantities, except the one under test, are kept relatively constant at their reference value.

Gaszähler - Turbinenradgaszähler

Dieses Dokument beschreibt die Messbedingungen, Anforderungen und Prüfungen hinsichtlich Konstruktion, Leistung und Sicherheit von axialen und radialen Klasse-1,0-Turbinenradgaszählern mit mechanischen Anzeigegeräten (im Folgenden „Zähler“ genannt) mit in der Hauptleitung liegenden Anschlüssen zur Durchflussmessung.
Dieses Dokument gilt für Turbinenradgaszähler, die zur Volumenmessung von Brenngasen der 1. und 2. Gasfamilie, deren Zusammensetzung in EN 437 angegeben ist, bei maximalen Arbeitsdrücken bis zu 420 bar, Betriebsdurchflüssen bis zu 25 000 m3/h über einen Gastemperaturbereich von mindestens 40 K und einem Umgebungstemperaturbereich von mindestens 50 K benutzt werden.
Dieses Dokument gilt für Zähler an Standorten, an denen unbedeutende Vibrationen und Stöße auftreten können, sowie an
—   geschlossenen Standorten (innen oder außen mit dem vom Hersteller vorgeschriebenen Schutz) mit oder ohne Betauung
oder, bei entsprechender Angabe durch den Hersteller, an
—   offenen Standorten (außen ohne Abdeckung) mit oder ohne Betauung
und an Standorten mit elektromagnetischen Störungen.
Soweit in diesem Dokument nicht anders angegeben:
—   sind alle dargestellten Drücke als Überdrücke zu verstehen;
—   werden alle Einflussgrößen außer der geprüften Einflussgröße relativ konstant bei ihrem Referenzwert gehalten.

Compteurs de gaz - Compteurs de gaz à turbine

Ce document définit les conditions de mesure, les exigences et les essais applicables à la construction, à la performance et à la sécurité des compteurs de gaz à turbine axiale et radiale de classe 1,0 munis d’indicateurs mécaniques, désignés ci-après sous l’appellation « compteurs », ayant des raccordements sur des canalisations en ligne pour mesure de débit des gaz.
Ce document s'applique aux compteurs de gaz à turbine utilisés pour mesurer le volume des gaz combustibles des 1ère et 2ème familles de gaz, dont la composition est spécifiée dans l’EN 437, à des pressions maximales de service allant jusqu'à 420 bar, à des débits réels allant jusqu'à 25 000 m³/h sur une plage de températures du gaz d’au moins 40 K et une plage de température d’environnement climatique d’au moins 50 K.
Ce document s'applique aux compteurs installés dans des emplacements où les vibrations et les chocs sont peu importants et :
-   dans des emplacements fermés (en intérieur ou en extérieur avec la protection spécifiée par le fabricant) avec ou sans condensation d'humidité ;
ou, si le constructeur le spécifie,
-   dans des emplacements ouverts (en extérieur sans protection) avec ou sans condensation d'humidité ;
ainsi que dans des emplacements avec interférences électromagnétiques.
Sauf spécification contraire dans le présent document :
-   toutes les pressions utilisées sont des pressions relatives ;
-   toutes les grandeurs d'influence, sauf celle qui est soumise à l'essai, sont maintenues relativement constantes à leur valeur de référence.

Plinomeri - Turbinski plinomeri

Ta dokument določa pogoje, zahteve, preskuse in pogoje merjenja za gradnjo, delovanje in varnost aksialnih in radialnih turbinskih plinomerov razreda 1,0 z mehanskimi kazalnimi napravami, v nadaljnjem besedilu merilniki, s serijskimi cevnimi priključki za merjenje pretoka plina.
Ta dokument se nanaša na turbinske plinomere, ki se uporabljajo za merjenje prostornine gorivnih plinov iz 1. in 2. družine, katerih sestava je določena v EN 437, pri največjem delovnem tlaku do 420 bar, dejanski hitrosti pretoka do 25 000 m3/h pri temperaturi plina preko 40 K in za klimatsko okoljsko temperaturo vsaj 50 K.
Ta dokument se nanaša na merilnike, ki so nameščeni na mestih, kjer so prisotni tresljaji in udarci majhnega pomena in v
– zaprtih lokacijah (znotraj ali na prostem z zaščito, kot jo določa proizvajalec) s kondenzirano ali nekondenzirano vlago, ali, če je tako določil proizvajalec,
– odprtih lokacijah (na prostem brez kakršnega koli prekritja) s kondenzirano ali nekondenzirano vlago in na lokacijah z elektromagnetnimi motnjami.
Razen če ni drugače določeno v tem dokumentu, velja:
– vsi uporabljeni tlaki so merjeni;
– vse vplivne količine, razen tistih, ki se preizkušajo, so pri njihovi referenčni vrednosti relativno konstantne.
