Economic Machined Acrylic Flowmeter - Series 7923

The Series 7923 acrylic flowmeters are an ideal low cost tool for measuring flow rates of inert and non-reactive gases. The 1/8” female standard inlet and outlet connections are contained in brass inserts to ensure a leak-free connection to prevent cracking of the acrylic body. A needle valve to control the flow rate is included. Flowmeters have a dual scale for air in SLPM and SCFH.

  • Maximum operating temperature: 150°F
  • Accuracy: ±5% full scale
  • Inlet and Outlet: 1/8" NPT female standard on 3" centers
