2500 Series

2500 Series Acrylic Tube Variable Area Flow Meters

Precision-machined acrylic. Economical liquid or gas measurement.

Models 2510 / 2520 / 2530 / 2540S or V / 2540I

Seeking an affordable solution for non-corrosive and low-pressure applications? Now there’s a clear choice: 2500 Series plastic variable area flow meters.

Constructed from precision-machined acrylic, 2500 Series flow meters use annealed, unibody construction that eliminates the leaks and panel detachment common with non-annealed, molded designs. An easy-to-read scale, rod-guided float and positive-stop valve ensure performance and safety. Choose from several valve, fitting, o-ring and float options to fit your specific project.

Features

  • Direct reading air or water scales available in English or metric scales
  • Measure flow rates from 40 ccm to 4000 lpm air and 4 ccm to 20 gpm water
  • Three accuracy levels to choose from: 2%, 3% or 5% Full Scale
  • Premium, threaded brass panel mounting inserts keep meter from detaching
  • Can be configured with a control valve (or no valve)
  • Fittings and valves available in brass, stainless steel or FNPT PVC pipe connections for in-line or panel mount
  • Removable back plate and hex head for wrench
