Abstract:
During the past decade a research test facility for the measurement of gas flow rates with a relative uncertainty of 0,1 % has been set up based on the laser Doppler technique. This facility has been used as an optical primary standard for gas under atmospheric pressure and flow rates up to 6500 m³/h. To measure flow rates for gas under high pressure directly and in a single step without staggered arrangements of several flow meters the laser Doppler technique has been applied to set up a new optical primary single-step standard for natural gas under high pressure.
