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.
This standard applies to meters 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 specified in this standard:
- all pressures used are gauge;
- all influence quantities, except the one under test, are kept relatively constant at their reference value.
