Improve Quality with Precision Gas Flow Control

As a manufacturer of capillary thermal mass flow controllers and meters for over 20 years, Sierra's advanced sensor technology offers thousands of customers precision gas flow control for improved quality in their research or process. What is the difference between other capillary-type mass flow controllers and our SmartTrak family of instruments? Each capillary flow meter from Sierra is designed so the physics are correct, resulting in excellent accuracy and repeatability. View Infographic to learn more about how mass flow improves accuracy.

Gas Measurement Versatility with Capillary MFCs

Our capillary thermal 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 ranges (i.e. 0 to 4 sccm), as well as higher, full-scale flow ranges up to 1000 slpm. Each capillary MFC offers precision mass flow control coupled with unsurpassed instrument stability, as well as :

  • 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. Explore related products and videos below.
