Pulsation effects on orifice measurement
- Pipeline and Compressor Research Council, Tulsa, OK (US)
The natural gas transmission industry has historically relied on the orifice as the contractual standard for custody transfer. The simplicity, reliability, low maintenance, rangeability (afforded by changing plate beta ratios) and repeatability of the orifice, together with reliable secondary systems, has dispelled flow measurement replacement attempts. While an influx of other meter types has occurred in recent years, the dominance of orifice meters dictate that any serious attempt at improved gas measurement accuracy must emphasize all phases of orifice meter installation. This paper reports on unsteady flow (pulsation) which can compromise orifice system accuracy. Instruments and error calculations for pulsation are reviewed.
