Envco – Environmental Equipment

The F-460N and F461N Inline Flowmeters are ideal for corrosive liquids where a meter with no metal in the fluid path is desirable.

These flowmeters feature a ribbed polysulfone body with precisely engineered guides for the Teflon® float. The easy to read dual flow scale (gpm and lpm) is printed directly on the meter body to maintain good visibility.

The F-460 series are available in flow ranges up to 5 gm with ¾" NPT(F) connections.
The larger, less restrictive F-461 models are available in fl ow ranges up to 35 gpm with 1" NPT(F) connectors.
