The Flowquip NFX glass tube variable area flow meter is ergonomically styled for todays modern flow installations and is available in three scale lengths. The NFX is suitable for liquid of gas measurement and customised scales can be provided to indicate flow rate in any desired engineering units. Flow rate can be accurately and reliably regulated by means of an integral needle valve and flow tubes can easily be removed from the flow meter frame for easy replacement or cleaning. The 1/4″ process connections can be either straight-through or rear entry (to enable panel mounting) and a polycarbonate cover is fitted to ensure operator safety in the event of a tube fracture.
