Abstract:
:The Gapmeter Lab Kit series of flowmeters has been calibrated using air. Two of the flowmeters were also calibrated using argon and oxygen as the priming gases. Linear calibration graphs have been obtained for all the Gapmeters. The two low flow Gapmeters are extremely susceptible to back-pressure.
