摘要：
An in situ calibration method for small Coriolis meters used for high-pressure gas flow calorimetry is presented. The method has an accuracy better than 0.02%, at level one standard deviation. Two meters, both with a totalizer function, have been evaluated, and the total long-term accuracy of the best meter is +/-0.11% at level one standard deviation.
