In today’s natural gas industry, it is of paramount importance that we focus on the accuracy and timeliness for the transfer of gas measurement data from the field measurement sites to a centralized gas measurement database to be verified, edited, and shared with all applicable groups. Measurement of wellhead deliveries, pipeline interconnects to town plants, city gates, and ultimately the end-user must be efficient and verifiable. To achieve this goal, various methodologies for gathering EGM data have evolved and improved over the past few years.
