ST75 Thermal Mass Flowmeter provides precise gas line control for industrial ovens and furnaces
Natural gas fuelled industrial ovens, heat chambers and furnaces are used in a wide variety of heating process applications. Two of the most common types of industrial ovens are the batch oven and the conveyor oven. Batch ovens support variable production load sizes, volumes and multiple temperature profiles where a high degree of process flexibility is desirable. Conveyor ovens, on the other hand, support highly repeatable temperature profiles with uniform, predictable volumes.
No matter the type of oven, heat chamber or furnace, they all benefit from the precise control of natural gas flow.
FCI’s ST75 Flow Meter helps process and plant engineers more accurately control their complex heating processes to optimise rise time, which lowers gas consumption and minimises plant energy costs. In addition, reducing natural gas consumption shrinks a plant’s carbon footprint to protect the environment.
The ST75 Flowmeter is equally well suited for low flow and high flow operations in industrial ovens and operates over a wide flow range, from 0.01 to 559 SCFM (0.01 to 950 NCMH) depending on line size. For variable process conditions, the ST75 is factory preset to a wide turndown range at 10:1 to 100:1.
With built-in temperature compensation, it 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 0.25 to 2 inches (6 to 51 mm). With a Vortab Flow Conditioner added as a spool piece, the Models ST75V or ST75AV are ideal for installations with limited straight-run and/or for operating in transitional flow ranges with accuracy of ± 1% reading, ± 0.5% full scale.
The ST75 Flowmeter 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.
