FCI’s ST80L Thermal Mass Flow Meter provides is a wide-ranging direct mass flow instrument, which is well suited for H2 measurement in small 1- to 2-inch (DN25-DN50) sizes in pressures up to 70 bar (g), 1000 psig. It features accuracy of up to ±1% of reading with ±0.5% repeatability over a wide flow range of 0.0062 to 838 SCFM (0,01 to 1425 Nm3/h) under variable process temperatures, making it ideal for measuring H2 and many other process gases and waste gases.
Hydrogen molecules are extremely small and can leak through the threaded connections typically provided with many flow meters. FCI’s ST80L inline flow meters, however, with their all-welded design in which the sensor is welded to the inline pipe spool eliminates concerns about potential instrument H2 leaks for user peace-of-mind. Additionally, the process connections of the inline pipe spool can be flanged or provided with a butt-weld joint that allows the inline thermal mass flowmeter to be welded directly into the user’s piping or application equipment.
The highly reliable ST80 Series Flow Meter also carries numerous agency approvals and certifications, including:, FM, FMc, ATEX, IECEx, UKCA (UKEX), SIL (IEC 61508), EAC/TR CU, EQM/ECAS, NEPSI, CE, CPA, CRN
