PROPOSED METHOD FOR GAUGE CALIBRATION BY A SERIES EXPANSION SYSTEM AT NML–CSIR, SOUTH AFRICA

• Abstract:

  There are various types of series expansion systems around the world, offering high accuracy for calibration of standards. The method investigated in this paper considers a much simpler system with a higher degree of certainty in measurements. The novelty of the method does not offer a new calculation, but rather a muchsimplified design Instead of using a high number of vessels, where the gas expands into, the system is limited to only two. The uncertainties will relate only to the pressure reduction factors or volume ratios and other known external factors.
