When you need premium high-performance mass flow control, but require the absolute lowest possible pressure drop, think SmartTrak 140. The 140 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. Accuracy and application flexibility result from:

– A patented, inherently linear Laminar Flow Element (LFE) design
– Advanced platinum-wound capillary sensor technology
– Proprietary frictionless-hovering control valve
