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