SmartTrak® 140 Ultra-Low ΔP Mass Flow Controllers


Jul 12, 2012

Get Incredible 4.5 psid (310 mBard) at Flows up to 500 slpm. When you need precision gas mass flow control of expensive process gases, where minimal pressure drop is a key consideration for cost savings and efficiency, the SmartTrak® 140 flow meter controls up to 500 slpm with an ultra-low ΔP of 4.5 psid (310 mBard) much better than typical ΔP values of 25 psid (1700 mBard) for equivalent mass flow controllers on the market.


  • Control 10 sccm to 500 slpm (nlpm) with 4.5 psid (310 mBard)

  • Competitively priced compared to other high flow controllers

  • Controls up to 500 slpm (nlpm) with an ultra-low ΔP of 4.5 psid (310 mBard)

  • Control valve with large flow coefficient (Cv) for precise digital PID control at low ΔP

  • Dial-A-Gas® Technology allows control of 10 pre-programmed gases in one instrument; substitute any gas

  • Pilot Module gives the customer a remote or local display and ability to change gas, engineering units, output signal, full-scale, set point, zero, span

  • All 316 stainless steel construction for increased durability

  • Patented, inherently linear Laminar Flow Element (LFE) for true linear performance
