Abstract

The components and testing results of working standard equipment for natural gas flow meter used multi-path ultrasonic meters in this paper. The testing results in different conditions by NMi of Netherlands, PTB of Germany and CVB of China showed that the uncertainties of the DN100 and DN300 meters for the standard equipment could meet the requirement of 0.5 % and 0.35 % respectively
