Precise gas line control for ovens and furnaces
The compact ST75 air/gas flowmeter (photo), which measures fuel gas, process gas, inert gas, waste gases and air in small line sizes, is suitable for optimizing 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 precise control of natural gas flow. The ST75 helps process and plant engineers more accurately control their complex heating processes to optimize rise time, which lowers gas consumption and minimizes plant energy costs. In addition, reducing natural gas consumption shrinks a plant’s carbon footprint to protect the environment. The ST75 is equally well suited for low- and high-flow operations in industrial ovens and operates over a wide flow range, from 0.01 to 559 std. ft3/min depending on line size. For variable process conditions, the ST75 is factory preset to a wide turndown range at 10:1 to 100:1. The ST75 flowmeter features accuracy to±2% of reading with±0.5% repeatability over varying process temperatures in line sizes from 0.25 to 2 in. — Fluid Components International (FCI), San Marcos, Calif.
