• 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).
