Gas meters - Diaphragm gas meters

Edition date: 2023-05-15
In Force
Summary: This European Standard specifies the requirements and tests for the construction, performance, safety and production of class 1,5 diaphragm gas meters (referred to as meters). This applies to meters with co-axial single pipe, or two pipe connections, that are used to measure volumes of fuel gases, which are within the limits of test gases of the 1st, 2nd and 3rd families described in EN 437. The meters have maximum working pressures not exceeding 0,5 bar and maximum actual flow rates not exceeding 160 m3.h−1 over a minimum ambient temperature range of −10 °C to 40 °C and a gas temperature range as specified by the manufacturer with a minimum range of 40 K. This standard applies to meters with and without built-in temperature conversion that are installed in locations with vibration and shocks of low significance (see MID Annex 1 Chapter 1.3.2 (a), class M1). It also applies to meters in: - closed locations (indoor or outdoor with protection as specified by the manufacturer) both with condensing humidity or with non-condensing humidity; or, if specified by the manufacturer: - open locations (outdoor without any covering) both with condensing humidity and with non-condensing humidity; - in locations with electromagnetic disturbances corresponding to those likely to be found in residential, commercial and light industrial buildings (see MID Annex 1 Chapter 1.3.3 (a), class E1). Unless otherwise stated, all pressures given in this document are gauge pressure. Requirements for electronic indexes, batteries, valves incorporated in the meter and other additional functionalities are given in EN 16314. Unless otherwise stated in a particular test, the tests are carried out on meters that include additional functionality devices intended by the manufacturer. Clauses 1 to 9 and Annexes B and C are for design and type testing only. NOTE The content of OIML Publication 'International Recommendation R 137' has been taken into account in the drafting of this standard. If no specific requirements are given for test equipment, the instruments used should be traceable to a national or international reference standard and the uncertainty (2σ) should be better than 1/5 of the maximum value of the parameter to be tested. For differential results the repeatability (2σ)/resolution should be better than 1/5 of the maximum value of the parameter to be tested.

La présente Norme européenne spécifie les exigences et les essais pour la fabrication, la performance, la sécurité et la production des compteurs de volume de gaz à parois déformables de classe 1,5 (ci-dessous désignés compteurs) mono-tubulaires co-axiaux ou bi-tubulaires utilisés pour mesurer des volumes de gaz combustibles de la 1ère, la 2ème ou la 3ème famille, conformément à l’EN 437:2003+A1:2009, à des pressions maximales de service ne dépassant pas 0,5 bar et à des débits maximum mesurés ne dépassant pas 160 m³/h, dans une plage minimum de température ambiante et de température du gaz allant de - 10 °C à +40 °C. Cette norme s’applique aux compteurs avec et sans compensation de température intégrée, qui sont installés dans des lieux avec vibrations et chocs de peu d’importance et dans  des lieux fermés (à l’intérieur ou à l’extérieur avec une protection spécifiée par le fabricant) dans des conditions d’humidité avec ou sans condensation ou, si cela est spécifié par le fabricant,  des lieux ouverts (à l’extérieur sans aucune protection) dans des conditions d’humidité avec ou sans condensation  dans des lieux à perturbations électromagnétiques correspondant à celles susceptibles de se trouver dans les bâtiments résidentiels, commerciaux et de l’industrie légère. Sauf indication contraire, toutes les pressions indiquées dans ce document sont des pressions relatives. Les Articles 1 à 9 et les Annexes B et D concernent seulement la conception et les essais d’approbation de type. Les exigences relatives aux totalisateurs électroniques, aux batteries, aux vannes intégrés dans le compteur, et aux fonctionnalités supplémentaires, sont indiquées dans l’EN 16314. NOTE Le contenu de la publication OIML « Recommandation Internationale R 137 » a été pris en compte lors de l’élaboration de cette norme. Les changements significatifs par rapport aux éditions précédentes comprennent ce qui suit :  conformité à la MID 2009/137/CE concernant les erreurs déclarées du même signe et l’essai de Qmin aux températures du gaz minimale et maximale déclarées ;  restructuration de la section sur la protection contre la corrosion ;  révision de l’essai d’endurance afin de refléter plus précisément les conditions de fonctionnement courantes ;  ajout d’exigences relatives aux compteurs non métalliques pour usage extérieur pour la prise en compte des différentes caractéristiques de matériaux ;  disposition relative aux compteurs avec totalisateurs électroniques et vannes d’arrêt intégrés ;  essai d’adhérence des étiquettes. L’Annexe A a été restructurée afin de stipuler des exigences supplémentaires pour les compteurs équipés d’un dispositif de compensation de température du gaz intégré. Lorsqu’aucune exigence spécifique n’est stipulée pour un équipement d’essai, il convient que les instruments utilisés soient référencés par rapport à une norme de référence nationale ou internationale et que l’incertitude (2 s) soit supérieure à 1/5e de la valeur maximale du paramètre à soumettre à l’essai. Pour les résultats différentiels, il convient que la répétabilité (2 s)/la résolution soit supérieure à 1/5e de la valeur maximale du paramètre à soumettre à l’essai.

Diese Europäische Norm legt die Anforderungen und Prüfungen für den Bau, den Betrieb, die Sicherheit und die Herstellung von Balgengaszählern der Genauigkeitsklasse 1,5 (im weiteren Zähler genannt) fest. Sie gilt für Zähler mit koaxialen Einstutzen- oder Zweistutzenanschlüssen zur Volumenmessung von Brenngasen aus der Gruppe der Prüfgase der 1., 2. und 3. Familie nach EN 437. Die Zähler weisen maximale Betriebsdrücke bis 0,5 bar und einen maximalen Durchfluss bis 160 m3∙h−1 über einen Umgebungstemperaturbereich von mindestens −10 °C bis 40 °C auf, sowie einen Gastemperaturbereich, der den Spezifikationen des Herstellers entspricht, jedoch mindestens 40 K umfasst. Die vorliegende Norm gilt für Zähler mit und ohne eingebaute Temperaturumwerter an Standorten mit nicht signifikanten Schwingungs- und Stoßbelastungen (siehe Messgeräte-Richtlinie, Anhang 1, Kapitel 1.3.2 (a), Klasse M1). Sie gilt weiterhin für Zähler an: - geschlossenen Standorten (innen oder außen mit dem vom Hersteller vorgeschriebenen Schutz) mit kondensierender Feuchtigkeit oder nicht kondensierender Feuchtigkeit; oder, bei entsprechender Angabe durch den Hersteller an: - offenen Standorten (außen ohne Abdeckung) mit kondensierender Feuchtigkeit und nicht kondensierender Feuchtigkeit; - sowie an Standorten mit elektromagnetischen Störungen, wie sie in Wohn- und Gewerbegebäuden sowie Gebäuden der Leichtindustrie auftreten können (siehe Messgeräte-Richtlinie, Anhang 1, Kapitel 1.3.3 (a), Klasse E1). Soweit in dieser Norm nicht anders angegeben, sind alle dargestellten Drücke als Überdrücke zu verstehen. Anforderungen an elektronische Zählwerke, Batterien, in den Zähler integrierte Ventile und andere Zusatzfunktionen sind in EN 16314 angegeben. Sofern für einen bestimmten Test nicht anderweitig angegeben, werden die Tests mit Zählern durchgeführt, die vom Hersteller vorgesehene Zusatzfunktionsgeräte besitzen. Die Abschnitte 1 bis 9 und die Anhänge B und C beziehen sich nur auf die Konstruktion und Typprüfung. ANMERKUNG Beim Entwurf dieser Norm wurden die Inhalte der OIML-Veröffentlichung "Internationale Empfehlung R 137" berücksichtigt. Falls keine spezifischen Anforderungen an die Prüfeinrichtung angegeben sind, sollten die verwendeten Geräte auf ein nationales oder internationales Bezugsnormal rückführbar sein und die Unsicherheit (2σ) sollte besser als 1/5 des Höchstwerts des zu prüfenden Parameters sein. Bei unterschiedlichen Ergebnissen sollte die Wiederholbarkeit (2σ)/Auflösung besser sein als 1/5 des Höchstwerts des zu prüfenden Parameters.
