The Gas Technology Institute (formerly the Gas Research Institute) sponsors a comprehensive flow measurement research, development, and commercialization (RD&C) program aimed at improving natural gas metering performance in the field. This paper summarizes some of the recent accomplishments of the research program at the Gas Technology Institute (GTI) Metering Research Facility (MRF), a high-accuracy natural gas flow calibration laboratory capable of simulating a wide range of operating conditions for the industry’s research, calibration, and testing needs. The MRF, located at Southwest Research Institute (SwRI) in San Antonio, Texas, supports a variety of GTI-sponsored research and third-party test and calibration activities. Major research initiatives currently being funded by GTI (formerly known as the Gas Research Institute or GRI) include ultrasonic and turbine flow meter research and gas sampling methods research. Over the past year, GTI has also funded Coriolis flow meter research and the development of a new energy flow rate meter concept. Through its portfolio of projects addressing priority research needs, the GTI natural gas measurement program provides significant benefits to the natural gas industry
