Flowmeter SmartTrak® 50 Series

FLOWMETH's and Sierra Instruments™ SmartTrak® 50 Series is a digital gas mass flow meter 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 metering at an OEM price, the 50 Series delivers by building on the same core sensor, LFE and sensor technology found in our award-winning Smart-Trak 100 Series, all backed by industry best off-the-shelf fast product delivery and FLOWMETH's and Sierra's style of personalized customer support. Our 50 Series has a standard accuracy of +/- 1.5% of full scale. It is our philosophy that core sensor technology must be of the highest quality and performance to make an excellent MFM. In contrast to the many wetted parts of CMOS and MEMS flow sensors, FLOWMETH and Sierra uses its most advanced 316L stainless steel platinum-wound capillary sensor technology ensuring the very best, dry mass flow measurement for nearly any clean gas. As a result, the 50 Series shares the same advanced sensor as the flagship Smart-Trak 100 Series, while incorporating a slightly varied laminar flow element design also inspired by the original Smart-Trak. A more efficient manufacturing process, a streamlined design, and our partnership with a very strong supplier base combined to make the 50 Series a reality.

Experience our passion for flow with the 50 Series in your next application.
