EN 1359膜式煤气表–标准概述

标准规定了对膜式燃气表的结构,性能和安全方面的要求及检测要求，包括同轴单管或双管连接，用来计量按照欧洲标准437:1993第1,第2和第3类燃料燃气的体积,在最小环境和燃气温度范围-5℃到+35℃内的最大工作压力在1巴以下和最大实际流量在160mh以内。

Scope:

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 m3h-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.
