Our Gas Flow Laboratory systems employ a time volume method to take measurements up to 60 SCFM
Our Gas Flow Laboratory systems employ a time volume method to take measurements up to 60 SCFM. Calibrations of mass flow controllers, mass flowmeters, rotameters, laminar flow elements and other gas flow monitoring devices can be performed with air, nitrogen, argon, helium, carbon dioxide, and specialty gases upon request.
  • Mass Flow Controllers
  • Mass Flowmeters
  • Variable Area Flowmeters
  • Gas Flow Monitors

A Brooks 20 cubic foot Bell Prover combined with Datametrics, Azonics, YSI, Logan, Druck and other instrumentation calculates flowrates up to 60 SCFM with an accuracy of +/- 0.2 percent. Lower flowrates are calibrated with an automated Sierra Cal Bench. The Sierra Cal Bench uses three precision bore quartz borosilicate glass tubes with frictionless mercury-sealed pistons monitored with sonar to achieve a range of 1.0 SCCM to 50000 SCCM with an accuracy of +/- 0.2 percent.

The lab also possesses a Bubble-o-Meter by Uson, which employs Druck, Datametrics, Logan and other instrumentation to take measurements up to 1 SCCM with an accuracy of +/- 0.7 percent.

All our calibrations come with Certificates of Calibration traceable to NIST, and our Quality Assurance Program meets MIL-STD-45662A, ANSI/NCSL Z540-1, 10CFR50 Appendix B, and is certified to ISO 9002-94.
