Precision-machined acrylic. Economical liquid or gas measurement. 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.
