Fluid ComponentsInternational”s ST75 flowmeter is a good fit for the measurement andmonitoring of fuel gases, such as natural gas, methane, and bio-gases,as well as air flows required for the efficient operation of a widerange of small line size-fed process equipment and plant-wide systems.The meter is an accurate, no-moving parts, direct mass flow instrumentthat is designed for easy, direct in-line installation in line sizesfrom 1/4″ to two inches (six to 51 mm). The meter services a wide flowrange from 0.008 to 839 SCFM (0.013 to 1425 NCMH), depending on linesize, with up to 100-to-one turndown ratio, which makes it equallywell suited for low-flow and high-flow applications. The meter provides+/- 2 percent of reading accuracy with +/- 0.5 percent repeatabilityand includes media temperature compensation to ensure continuousperformance in industrial environments. Standard outputs are fullyscaleable 4-20 mA and 0-10 V that are user assignable to flowrateand/or temperature and a 0-1 kHz pulse output of total flow. Themeter is enclosed in a rugged, all-metal, dust- and water-resistant,NEMA Type 4X (IP66)-rated package that is designed for hazardous-areainstallations.
