The F-400N Series Variable Area Flowmeters have been very popular flowmeters for a long time.  These variable area flowmeters feature superior styling, quality materials and a variety of options.  F-400N Series variable area flowmeters are machined of the highest quality acrylic which is polished to a crystal clear finish.  Additional variable area flowmeter design features include: Corrosion and wear resistant internal parts, sturdy well built adapters and Viton o-ring seals.  Permanent scales are screen printed onto the variable area flowmeter body, directly in front of the float for easy reading. 

Other variable area flowmeter series, configurations and flow ranges are available.  To select a variable area flowmeter other than what we list here we need the desired mounting configuration, liquid being measured, and measurement range in GPM, LPM or SCFM. 

Variable Area Flowmeters are tested and calibrated for water or air only.  Although variable area flowmeters may be suitable for other chemicals, it is the responsibility of the user to determine the suitability of the variable area flowmeter in their application.
