Gas Flow Calibrations
|
The WGFS uses critical venturis and critical nozzles that have been calibrated in the PVTt standards as working standards or reference flow meters to calibrate customer flow meters. The uncertainty of the WGFS is 0.1% at flows less than 2000 L/min and 0.12% at flows larger than 2000 L/min. Pressure regulators provide CFV pressures up to 700 kPa. The gas source for the WGFS can be dried air from our compressor, nitrogen from a dewar (<150 L/min), or other gases from compressed gas cylinders (<100 L/min).
To read more about the principles of operation and uncertainties of our gas flow standards and see sample calibration reports see our Technical Notes and Publications.
<>Fittings available include national pipe thread (NPT), SwagelokTM, VCR, VCO, AN 37 degree flare, ASA 150 lb, ASA 300 lb, and ASA 600 lb and pipe diameters range from 3 mm to 203 mm (1/8" to 8").
Turnaround time for a single
flow meter is approximately 4 weeks:
However, please contact Gina Kline to schedule the calibration of your instrument(s).
