| The SwRI Metering Research Facility (MRF) is a world-class, high-accuracy natural gas flow measurement facility used for flow meter development, calibration, and testing. Test conditions closely simulate those found in the field. Key features of the MRF include (1) measurement traceability to the U.S. National Institute of Standards and Technology, (2) high-precision measurement accuracy, and (3) a broad range of test conditions (i.e., test gas pressures between 15 and 1,200 psig, test gas temperatures between 45 and 120 degrees Fahrenheit, and flow rates up to 1,650,000 standard cubic feet per day). |
