Gasification flow meter

Fluid Components International’s (FCI) ST75 Series Air/Gas Flow Meter operates in rugged, hot, biomass gasification plant environments to provide measurement of mixed composition gases including hydrogen (H2), carbon monoxide (CO), and trace methane (CH4) with highly dependable accuracy to ±2% of reading with ±0.5% repeatability in line sizes from 0.25 to 2 inches (6 to 51 mm). 

 

With its thermal dispersion mass flow sensing element, the ST75 Flow Meter measures mixed composition gases, and is safe for potentially flammable or explosive combustible gas environments. The ST75 Flow Meter operates over a wide flow range in mixed gas environments from 0.01 to 559 SCFM (0.01 to 950 NCMH), depending on line size. For variable process conditions such as those in biomass gasification plants, the ST75 meter is factory preset to a turndown range of 10:1 to 100:1. 

 

The ST75 Flow Meter’s fully scalable dual 4-20mA standard outputs are user assignable to flow rate and/or temperature and a 0-1kHz pulse output of total flow. It withstands process temperatures from 0°F to 250°F (-18°C to 121°C). It operates at pressures up to 240 psig [16.5 bar (g)] with a standard t-fitting (NPT female) process connection. With a tube process connection, the meter withstands 600 psig [41 bar (g)].

 

Offering direct-flow measurement for higher performance at a lower cost with proven thermal dispersion technology, the ST75 Flow Meter eliminates the need for additional pressure and temperature sensors, flow computers, or other devices that are required with orifice plates, Venturis, Vortex shedding, and other volumetric meters. The ST75 meter also requires virtually no maintenance for both a low installed and low life-cycle cost.
