Gas meters - Rotary displacement gas meters
This European Standard specifies ranges, construction, performances, output characteristics and testing of rotary displacement gas meters (hereinafter referred to as RD meters or simply meters) for gas volume measurement.
This European Standard applies to rotary displacement gas meters used to measure the volume of fuel gases of the 1st, 2nd and 3rd gas families, the composition of which is specified in EN 437, at a maximum working pressure up to and including16 bar over a gas temperature range of at least -10 °C to +40 °C.
Unless otherwise specified in this standard, all pressures used are gauge pressures.
Gaszähler - Drehkolbengaszähler
Diese Europäische Norm legt den Einsatzbereich, den Bau, den Betrieb, die Ausgabecharakteristiken und die Prüfung von Drehkolbengaszählern (nachfolgend RD-Zähler oder einfach nur Zähler genannt) für die Gasvolumenmessung fest.
Diese Europäische Norm gilt für Drehkolbenzähler, die für die Volumenmessung von Brenngasen der 1., 2. und 3. Gasfamilie, deren Zusammensetzung in EN 437 beschrieben ist, bei einem maximalen Betriebsdruck bis einschließlich 16 bar in einem Gastemperaturbereich von mindestens - 10 °C bis + 40 °C eingesetzt werden.
Soweit in dieser Norm nicht anders angegeben, handelt es sich bei den dargestellten Drücken um Überdrücke.
Compteurs de gaz - Compteurs de gaz a déplacement rotatifs
La présente norme définit les gammes, construction, performances, caractéristiques des sorties et essais des compteurs de mesure de volume de gaz à pistons rotatifs (appelés ci-après simplement compteurs). La présente norme s'applique aux compteurs de gaz susceptibles de recevoir une approbation de qualification CEN; pour des gaz combustibles de la 1ère, 2ème et 3ème famille de gaz pour des pressions jusqu'à pmax = 16 bar; pour une gamme minimum de température de -10 °C à +40 °C.
