Improved Mass Flow Control Performance for Improved Quality

Our mass flow controllers and meters control and measure the mass flow rate of any clean dry gas, including mixtures, toxics and corrosives to very low-flow, flow ranges (i.e. 0 to 4 sccm) as well as higher, full-scale flow ranges up to 1000 slpm. Each digital mass flow controller offers precision flow control coupled with unsurpassed instrument stability, as well as:

  • Our patented, inherently linear Laminar Flow Element (LFE) design
  • Advanced platinum-wound capillary sensor technology
  • Proprietary frictionless, hovering control valve mass flow control valve that is both reliable and flexible

Whether you’re in research, the automotive industry, aerospace, or medical devices, precision data you can rely on makes your job easier. Learn more about popular flow applications.
