Flow Sensors

They're designed to measure air, oxygen, and other gases for embedded applications. The compact size and standard configurations make it easy to design them into your products.

TSI embedded mass flow sensors are optimized for medical applications with respiratory products being an ideal fit for TSI technology. Since 1983, TSI flow sensors have been used in patient ventilators around the world due to the unique TSI technology and performance. TSI flow sensors are trusted as reliable, accurate, and cost effective for use in ventilator applications ranging from adult to neonatal.
