The Tylan FC-260 Mass Flow Controller delivers precision gas flow regulation for oxygen in air at 500 SCCM with maximum operating pressure of 150 PSIG. This elastomer-sealed unit combines an attitude-insensitive flow sensor, superior bypass design, and solid-state valve assembly to achieve 1% full-scale accuracy without external pressure or temperature corrections. The FC-260 operates across a 5–43°C temperature range and accepts control signals via 0–5 VDC command voltage. It integrates into automated process systems requiring repeatable, reliable gas metering.
