The FS10i flowmeter series (photo) is designed to measure the flowrate of natural gas. The FS10i meter is accurate to±1.5% of reading,±0.5% of full scale, with repeatability of±0.5% of reading and has a response time of 4 s. Designed with highly stable direct mass-flow sensors, FS10i flowmeters require no additional pressure or temperature sensors or other components to infer flow measurement. The sensor does not foul or clog, and requires no routine maintenance, ensuring continuous operation. FS10i flowmeters provide a fluid-matched, calibrated and linearized 4–20-mA output of flowrate, and a user-programmable high- or low-flow alarm or trip point. For visual indication, the flowmeters include a 10-segment LED array display that illuminates proportionally to the flowrate and flashes if an alarm trip occurs. Available in both inline and insertion-style configurations, FS10i meters support installation in line sizes from 1 to 20 in. (DN25 to DN500). They operate over a wide turndown ratio from 1 to 400 std. ft3/min, depending on fluid media and line size. Their 316L stainless-steel construction ensures corrosion resistance. — Fluid Components International LLC (FCI), San Marcos, Calif.
