Helpful Conversions:
For Gas:
For Liquid:
LPM x 1000 = CCM LPM x 1000 = CCM
CFH x 472 = CCM GPH x 63.09 = CCM
CFM x 28230 = CCM GPM x 3785 = CCM
For Pressure: For Temperature:
ATM x 14.696 = PSI ºC = (ºF-32) x 0.555
ATM x 101.325 = KPA ºF = (1.8 x ºC) + 32
ATM x 29.92 = IN of Hg ºK = ºC + 273.15

DESCRIPTION
Series GD is a direct read flowmeter for liquids or gases
available in either 65 or 150 mm scale lengths. Series GD
flowmeters can be configured with a standard or precision
control valve on either the inlet or no valve at all; fittings
can be specified in either aluminum or stainless steel; valves
can be specified in either brass or stainless steel; O-rings
and seals can be provided in Buna-N, Viton
® or other
optional elastomers.
