EN 12480:2002
(Main)Gas meters - Rotary displacement gas meters
General Information
- Abstract
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.
