TYPES OF METERS

This standard and its specifications are limited to the following two types of orifice meters:

1. Orifice meters with circular orifices located concentrically in the meter tube having upstream and downstream pressure taps as specified for flange taps in Section 14.3.3.

2. Orifice meters with circular orifices located concentrically in the meter tube having upstream and downstream pressure taps as specified for pipe taps in Section 14.3.3.

TYPES OF HARDWARE

This standard covers the measurement of natural gas and other fluids associated with the production, processing, transportation, and distribution of natural gas by orifice meter as related to the primary element (that is, the orifice plate and the meter tube consisting of the orifice flanges or fittings, flow conditioners, and the adjacent pipe sections) and the methods of flow calculation. This standard does not cover the equipment used in the determination of the pressures, temperatures, and other variables, which must be known for the accurate measurement of the flow of fluids in pipe lines. Publications by the American Gas Association, the American Petroleum Institute, and others may be used as a guide.
