Launch Calculator ↗Precision Engineering by SCHMIDT
SCHMIDT Technology, a globally trusted German brand, is a pioneer in precision-engineered thermal mass flow sensors for the accurate measurement of air and gases across industrial and utility applications.
With more than 35 years of expertise, SCHMIDT flow sensors deliver unmatched accuracy and long-term stability for compressed air and a wide range of gases, including compressed air, nitrogen, oxygen, argon, carbon dioxide, methane, natural gas, helium, and biogas.
Engineered on the thermal anemometer principle, SCHMIDT sensors directly measure mass flow and velocity without requiring separate pressure or temperature compensation. This makes them ideal for energy monitoring, leak detection, process control, and cleanroom applications, providing reliable performance even in demanding industrial environments.
