ST80 Thermal Mass Flow Meter
Brand: Fluid Components International LLC (FCI)Fluid Components ST80 flow meters combine proprietary equal mass thermal dispersion flow sensing elements, precision electronics, and exacting fluid calibrations, all packaged within rugged, industrial enclosures.
The ST80 Series delivers a superior air/gas flow measurement solution that continuously meets performance specifications in the most demanding process and plant applications with virtually no scheduled maintenance.
FCI’s ST80 Series features an accuracy of ±1% of reading, 0.5% of full scale and repeatability of ±0.5% of reading. The turndown ratio is factory preset to your application from a minimum of 2:1 to a maximum of 100:1 and is field adjustable within the calibrated range.
ST80 flow meters are offered in a wide range of packaging options, mounting and installation options that ensure configuration matched to your exact application conditions. From compressed air to hydrocarbon gases, single gases to biogas mixtures, ST80 flow meters are at work improving processes throughout the world.
