本欧洲标准规定了使用同轴单管或两个管道连接的1,0级和1,5级电池供电的超声波气体计（以下称为米）的结构，性能和安全性的要求和测试，测量第二和/或第三系列的分布式燃料气体的体积，如EN 437中给出的最大工作压力不超过0.5巴），最大实际流量在最小环境温度下可达10 m3/h范围为-10°C至40°C，最低气温为40 K，适用于国内应用。本欧洲标准适用于测量元件和寄存器被封装在同一种情况下的仪表。 本欧洲标准适用于具有和不具有内置温度转换的仪表，其安装在振动和震动低的位置，并且在 ²，关闭位置（室内或室外，具有制造商规定的保护），具有冷凝或非冷凝湿度 或者，如果制造商规定， ï,¾有冷凝湿度或非冷凝湿度的开放位置（室外无覆盖） 并在具有电磁干扰的位置。 除非另有说明，本欧洲标准中给出的所有压力都是测量值

This European Standard specifies requirements and tests for the construction, performance and safety of class 1,0 and class 1,5 battery powered ultrasonic gas meters (hereinafter referred to as meters), having co-axial single pipe, or two pipe connections, used to measure volumes of distributed fuel gases of the second and/or third family, as given in EN 437, at maximum working pressures not exceeding 0,5 bar ) and maximum actual flow rates of up to 10 m3/h over a minimum ambient temperature range of -10 °C to +40 °C, and minimum gas temperature span of 40 K, for domestic applications. This European Standard applies to meters where the measuring element and the register(s) are enclosed in the same case. This European Standard applies to meters with and without built-in temperature conversion, 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 stated, all pressures given in this European Standard are gauge pressures. When more than one meter type is submitted for testing, then each meter type is required to be tested against this European Standard. Clauses 1 to 15 and Annex C are for design and type testing only. NOTE See Annex A for production requirements.
