(*) Air flow rates in standard units are at 70'F and 14.7 PSIA, air flow rates in normal units are at 1.013 bar & 20'C
(**) When the viscosity of the fluid exceeds the viscosity immunity ceiling (VIC), a calculated correction is applied to account for
the difference between factory calibration fluid and process fluid.

(*) Minimum operating downstream pressure for gas service in PSIG.
(**) Viscosity immunity ceiling listed is for stainless steel float, fluid specific gravity 1.0. When the viscosity of the fluid exceeds the viscosity immunity
ceiling (VIC), a calculated correction is applied to account for the difference between factory calibration fluid and proc
ess fluid.
(****) Extended range - nonviscosity compensating floats.
(*****) Air flow rates in standard units are at 70'F and 14.7 PSIA, air flow rates in normal units are at 1.013 bar & 20'C
