The error curve of the volume-conversion devices and gas meters

Cimerman, Franc (avtor), Širok, Brane (avtor), Blagojević, Bogdan (avtor)

The accurate measurement of standard or normal volumes of natural gas relies on the precision of gas meters and volume conversion devices (VCDs) or correctors. VCDs are calibrated based on PTB – Prüfregeln: Band 20 or EN 12405–1. Utilizing Experimental Design Theory, we can predict the error curve of volume correctors fc as a function of absolute pressure and temperature. The gas meters are usually calibrated at the working pressure of natural gas at different flow rates according to the PTB – Prüfregeln: Band 30. By applying the principles of Experimental Design Theory, we were able to determine the error curve fV of a gas meter as a function of both flow rate and absolute pressure. The standard error of the estimate SEE serves as the measure to evaluate the suitability of approximating the error curve of volume correctors and gas meters. The proposed testing procedure can be automated for increased efficiency.
