The ST51 supports BACT (Best Available Control Technology) practices, which require technologies that achieve the maximum degree of emissions control that can be achieved by a particular facility and is based on a case-by-case decision that takes into account technical feasibility, cost and other energy, environmental and economic impacts. The ST51 Flow Meter is ideal for the measurement and monitoring of industrial plant greenhouse gases. The ST51 features a no-moving parts design that’s non-clogging and operates across a wide flow range with low-flow sensitivity. It’s packaged in an explosion-proof transmitter, and the calibration is matched to the user’s actual gas composition and installation conditions.
FCI designed the ST51 Flow Meter to measure and monitor GHG per the EPA’s requirements. It features a thermal mass, insertion-style flow element with flow accuracy to ±1 percent of reading across a broad flow range from 0.3-400 sfps (0.08-122 MPS), and repeatability of ±0.5 percent of reading. The flow element is available for use in line sizes from 2?-24? (51 mm-610 mm). It operates across a wide turndown range of 100:1 and at temperatures from 0°F to 250°F (18°C to 121°C). It withstands pressures up to 500 psig [34 bar (g)].
The ST51 Flow Meter’s robust thermal mass flow sensing element has no moving parts and no orifices to clog or foul to attain virtually maintenance-free service in wet, dirty biogas applications.
The flow element is constructed with a 316L stainless steel body and Hastelloy C-22 thermowell sensors to resist corrosion. It includes built-in temperature compensation circuitry for accurate, repeatable measurement year-round as temperatures rise and fall seasonally.
The ST51 is available through FCI’s GHG Reporting Fast Track Initiative, which is a three-prong program. A special toll free GHG Hotline is now available at 800-863-8704, ext 218 to answer flow meter questions. The hotline is staffed by FCI’s Flow Meter Applications Group, which includes experts in GHG measurement and stack gas monitoring.
