Production Equipment Effects of Gas Measurement The condition of gas as it presents itself in the pipeline is often not ideal for accurate measurement, by an orifice flow meter. It is the requirement of the American Gas Association (AGA) that the natural gas be in a single phase and with a swirl-free fully developed profile as it passes across the orifice…

How Not to Measure Gas/Orifice Flow Meters Measuring natural gas is both a science and an art. Guidelines and industry practices explain how to accurately measure natural gas. The ‘art” comes in trying to minimize errors and prevent measurement problems. However, sometime it’s easier to explain “how not” to measure gas when reviewing measurement errors. Measurement errors can be caused through poor…

Overall Measurement Accuracy This paper presents methods for determining the uncertainty of both differential and linear metering stations. It takes into account the type of meter, number of meters in parallel, type of secondary instruments, and the determination of physical properties. The paper then relates this information to potential influence on system balance
