Reference nozzle calibration rig on natural gas SPU-PG-2M

In 2003, the design bureau specialists together with the metrology service have developed a nozzle calibration rig on natural gas.

The calibration rig is used for calibration, verification and testing of gas flowmeters and meters of different operating principles in the gas flowrate range from 1 to 16000 m3/h. Measurement error is ± 0.3%. The reference instruments for gas flowrate and volume measurements are 9 critical nozzles, which can be connected by means of shutoff and control valves, ensuring their automatic activation in any combination.
