FCI ST75 air/gas flow meter
FCI’s compact ST75 air/gas flow meter, which measures fuel gas, process gas, inert gas, waste gases and air in small line sizes, is suitable for optimising natural gas flow control for industrial ovens, heat chambers and furnaces to reduce process and plant fuel costs.
No matter the type of oven, heat chamber or furnace, they all benefit from the control of natural gas flow. The flow meter helps process and plant engineers control their complex heating processes to optimise rise time, thus lowering gas consumption and minimising plant energy costs. In addition, reducing natural gas consumption shrinks a plant’s carbon footprint to protect the environment.
The flow meter is equally suited to low- and high-flow operations in industrial ovens and operates over a wide flow range, from 0.01 to 950 NCMH depending on line size. For variable process conditions, the product is factory preset to a wide turndown range at 10:1 to 100:1.
With built-in temperature compensation, the flow meter maintains consistent performance in rugged, hot industrial process environments. It features accuracy to ±2% of reading with ±0.5% repeatability over varying process temperatures in line sizes from 6 to 51 mm. With a Vortab Flow Conditioner added as a spool piece, the models ST75V or ST75AV are suitable for installations with limited straight-run and/or for operating in transitional flow ranges with accuracy of ±1% reading, ±0.5% full scale.
The flow meter’s precision flow element has a no-moving parts design that employs platinum RTD sensors embedded in equal mass thermowells with microprocessor electronics calibrated to laboratory standards for a wide range of gases. It features remote mounting capabilities for hazardous or crowded plant environments; the remote mount transmitter, which includes a full digital display, can be mounted up to 15 m away from its thermal mass flow sensor in the process piping and connected via two 0.5″ FNPT or M conduit connections.
Offering direct-flow measurement with thermal dispersion technology, the 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. It requires virtually no maintenance.
