Abstract: A new high-pressure test facility was constructed for calibrating ANSI Class 300 and 600 gas turbine meters ranging in size from 3 to 8 inch on natural gas. Meters can be tested over a 20 to 1 flow rate range up to 72,000 ft3/h at pressures between 200 and 1000 psig with natural gas and between 0 and 150 psig with air. The transfer standards used in the facility are selfproving dual-rotor turbine meters. Dualrotor turbine meters offer a novel approach in a laboratory standard because continuous monitoring of the master meter performance is possible. Comparing the output frequency from the main rotor to the checking rotor in the master meter provides an immediate means of determining a change in the calibration of the transfer standard. Thus the reliability of the transfer standard used in this facility is improved over conventional turbine meters by using this process control technique.
