Fluid Components International ST51 air/gas flowmeter

The ST51 air/gas flowmeter from Fluid Components International (FCI) provides industrial plant engineers with a solution for greenhouse gas (GHG) monitoring and supports the EPA’s BACT (Best Available Control Technology) initiative in the US. The flowmeter is suitable for the measurement and monitoring of industrial plant greenhouse gases. It features a no-moving-parts design that’s non-clogging and operates over a wide flow range with low-flow sensitivity. Packaged in an explosion-proof transmitter, the calibration is matched to the user’s actual gas composition and installation conditions.

The thermal mass, insertion-style flow element features flow accuracy to ±1% of reading over a broad flow range from 0.08 to 122 m/s and repeatability of ±0.5% of reading. The flow element is available for use in line sizes from 51 to 610 mm. It operates over a wide turndown range of 100:1 and at temperatures from -18 to 121°C. It withstands pressures up to 34 bar (g).

Dual 4-20 mA analog outputs are user assignable to flow rate and/or temperature, and there is a 0-1 kHz pulse output for totalised flow. The transmitter’s digital communications include an RS-232C port, and with units that have the digital display option there is a wireless IR link for PDA use.
