Abstract: Commercial and domestic gas usage is measured primarily by rotary, turbine and diaphragm type meters. The responsibility to provide accurate meters to assure correct billing is one that utility companies have always recognized and responded to. Of course, in recent years the emphasis on accurate measurements has increased as users became concerned with the impact of the spiraling cost of gas. The billing meter accuracy is often questioned in billing disputes. The ability of a utility company to prove accuracy of billing meters is essential to billing credibility. Specific calibration capabilities required of utility companies are most often outlined by PUC Commissions. This paper reviews common approaches to calibration of billing meters. An alternative approach to these methods is introduced utilizing Laminar Flow Elements (LFE) type primary elements. It will be shown that the LFE provides benefits such as ease of use, accuracy, cost effectiveness and portability.
