(*) Minimum operating downstream pressure for gas service (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 process fluid.
Note 1: All size 8-13 floats listed are 316 SS with integral magnet for use with reed switch alarm.
(***) Alarm option for sizes 2 and 6 requires metallic float (SS or carboloy) for use with inductive type alarm.
(****) 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
