Erdco Armor-Flo 3400 Variable Area Flow Meter

Erdco Armor-Flo 3400 variable area flow meter handles fluids that cannot be measured with the See-Flo® due to clarity, pressure or compatibility with wetted materials. The wedge shape of the meter body housing provides the Armor-FloTM with the same self-cleaning characteristics as the See-Flo®. Teflon® encapsulated cobalt magnets are used to couple the flow isolated indicator with the vane. These features emphasize simplicity and reduce maintenance.
