Flow Measurement Services

The Metering Research Facility (MRF) is a world-class, high-accuracy, high-technology flow measurement facility for meter development, meter calibration, and meter testing – simulating actual field operational conditions. The MRF facility provides the highest accuracy, controllability, and rangeability in the industry.

 

The MRF is owned and operated by Southwest Research Institute (SwRI). As the only facility of its type in North America, the MRF has two separate flow test systems for achieving the highest accuracy, controllability, and rangeability:

MRF closed-loop systems (HPL and LPL)

  • High-Pressure Loop (HPL) for large diameter pipe (2–16 inches, 150–1,100 psig) high pressure/volume metering applications

  • Low-Pressure Loop (LPL) for smaller diameter pipe (1–10 inches, 30–175 psig) lower pressure/volume metering applications

The HPL and LPL are closed-loop recirculating flow loops. Processed natural gas is used for the majority of tests. Other fluids, such as nitrogen and carbon dioxide, are also available. Both systems are located at the same site and operated from a single control center. Flow meter calibrations performed at the MRF are traceable to the U.S. National Institute of Standards and Technology (NIST).
