2001 Series Acrylic Tube Variable Area Flow Meters

The most economical liquid or gas measurement for non-corrosive applications.
Models 2001D2 / 2001D4 / 2001D6

The 2001 Series flow meters provide a means of indication at the lowest cost for non-corrosive flow applications. The tapered metering tube is integrally machined in the acrylic body while a standard direct reading scale engraved on the body affords maximum simplicity of installation and operation. Available options include integral needle control valves, as well as flow controllers on the inlet or outlet.
