SmartTrak 50 – Economical OEM Digital Mass Flow Controller

Low-Cost Digital Mass Flow Controllers & Mass Flow Meters

Sierra Instruments’ SmartTrak® 50 Series is a digital gas mass flow controller designed to meet the low-cost budgetary requirements of OEM’s while maintaining excellent quality and performance. Inspired by the need for accurate and reliable gas mass flow control at an OEM price, the 50 Series delivers by building on the same core sensor, LFE and valve technology found in our award-winning SmartTrak 100 Series, all backed by industry best off-the-shelf fast product delivery and Sierra’s style of personalized customer support. Our 50 Series has a standard accuracy of +/- 1.0% of full scale. The flexible and powerful direct-acting control valve sets it apart from the competition by minimizing leak-by, while offering a 300 ms response time to setpoint changes at +/- 0.25% repeatability.
