Conoflow Sight Feed Assembly

The Conoflow Sight Feed Assembly is the standard regulator to control bubbler system gas flow rates. It consists of a Conoflow differential gas regulator, a sight-fed glass, bypass purge tubing and valve assembly.

The diaphragm of this regulator acts on a soft-seated plug to admit just enough gas to maintain a pressure drop of 1.5 PSI across the needle valve. This ensures a constant gas flow rate even under changing water levels (pressures). The glass sight feed is filled with silicone oil so the bubble rate can be observed and set.

Silicone oil ordered seperately.
