EN 1359 Diaphragm gas meters–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.
