Reference nozzle calibration rig on air UPSG-1600
The UPSG-1600 unit is used for calibration of industrial gas meters with the upper measurement limit up to 1600 mЗ/h. The unit use is regulated by the calibration diagram of GOST R8.618-2006, where the unit is classified as working references of the second category.
The calibration rig operating principle is based on comparison of the results of simultaneous measurements of the calibration medium flow rate (volume), reproduced by the unit, flowmetercounter
being calibrated and the reference measuring instrument, connected in series in measurement mainlines.
