American Gas Association states that measurement of natural gas by an orifice meter requires a single-phase hydrocarbon through the metering area, which allows an accurate measurement of differential pressure across the orifice plate, flowing temperature, and component analysis at a metering station. Some gas contracts state that the producer shall condition the gas for metering which would allow accurate measurement of gas flowing through the metering station. To meet the AGA and Contract requirements personnel need to have a knowledge and operational understanding of production equipment used to condition gas prior to the point of measurement. To achieve this condition, field personnel should have an operational understanding of production equipment by which they can perform maintenance on and make adjustments to achieving an optimum flowing condition within the metering tube
