Abstract
The focus of this research was to examine a novel method for calibrating natural gas flow meters. This new method can accommodate very large flow rates and it avoids common problems associated with current meter proving techniques. In this method, the amount of gas accumulated in a vessel of fixed. volume is determined by measuring the change in capacitance of the vessel with respect to time. Because the accumulator has a fixed volume, the problems inherent with the mechanical motions involved in volumetric provers such as bell provers and piston provers are eliminated. Accurate measurements can also be made in larger vessels than would be feasible for gravimetric provers, especially for in situ calibrations.
