Thermal Mass Gas Flow Meters

FCI Gas Mass Flow Meters FCI designs, manufactures and sells a broad line of thermal mass flow meters for air and gas flow measurement. Thermal mass flow meter technology utilizes the relationship between flow rate and cooling effect for direct measurement of mass flow.  With no moving parts and minimal invasiveness, thermal flow meters provide a highly repeatable, accurate, low cost, easy to install solution for air and gas flow measurements.  FCI provides flow meters suitable for applications in pipes and ducts, as small as 1/4 inch [6mm] to the largest of stacks.

FCI thermal mass flow meters feature precision, surface-mount, RoHS compliant electronics with industry leading functions, such as AST (available in models ST80 and ST100), and communications capabilities, and with un-matched agency approvals and certifications.  Whether standard analog outputs like 4-20mA or pulse, or digital bus communications of HART, Foundation Fieldbus, PROFIBUS, Modbus and more, FCI has a thermal flow meter solution. Transmitter enclosures are industry’s most rugged and tested, and carry global agency approvals that ensure longest service life and safe operation in the most demanding process and plant applications.   You will find FCI thermal flow meters with agency approvals from FM, FMc/CSA, ATEX, IECEx, EAC, NEPSI, Inmetro, UKEX, ECAS, and more, and industry or country specific pedigrees such as SIL (IEC 61508), CRN, PED, AMS per EN15267 (QAL1), CEMS and more.

FCI provides several thermal mass flow meter product families and more than 20 models to meet a broad range of performance, pipe diameters, gas types and environmental application requirements.
