It will be used to calibrate reference flow meters from 1 to 200 g/h. By setting up an uncertainty budget for this setup, the calibration of the instruments can be compared to that of NMI’s (National Metrology Institutes).

For a CFV, typical calibration set points are at 200 kPa, 300 kPa, 400 kPa, 500 kPa, and 600 kPa. A laminar flow meter is normally calibrated at 10 %, 25 %, 50 %, 75 %, and 100 % of the meter full scale. how to take fingerprint for oci card
