SmartTrak 140 Ultra-Low ΔP Mass Flow Controller

By combining these two technologies, the SmartTrak 140 boasts the smallest pressure drop in the industry and includes all the features of FLOWMETH's and Sierra’s flagship SmartTrak 100 Series. Dial-A-Gas® Technology allows users to set zero, span, and full scale for 10 different gases independently in the field. A hand-held or instrument-mounted user display/interface called the Pilot Module makes field-adjustments and re-configuration easy. Precision gas mass flow control at higher flow rates, typically greater than 300 slpm (nlpm), relies on a large pressure differential (ΔP) across the control valve, especially with the small flow bodies and control valves commonly used in capillary-type thermal mass flow controllers. In all cases, especially with expensive high purity gases used in the semiconductor industry, maintaining initial pressurization of the gas is critical until it is eventually put to work in the tool. This is where the reduction of functional efficiency and resulting financial losses can occur. The SmartTrak 140 was specifically designed to improve efficiency in these types of applications. So, when you need premium high performance mass flow control, but require the absolute lowest possible pressure drop, think our SmartTrak 140 is the optimal solution.
