Rare earth cobalt magnets are used to couple the flow isolated indicator with the vane. There are no shaft connections or stuffing boxes. The internal wedge shape of the Armor-Flo housing is designed for self-cleaning. These features emphasize simplicity and reduce maintenance.
Each flowmeter is calibrated to be direct reading for a liquid or gas at it's operating conditions. The large indicator and dial are easy to read. Scales with special engineering units and dual units of measure are available.
