MT100 Series multipoint thermal mass flowmeters (photo) provide temperature-compensated direct mass-flow measurement of air and gases in large-diameter pipes, stacks and rectangular duct installations, where there are often challenges in achieving successful flowmeter installation and performance. To help overcome issues associated with distorted flow profiles, low flowrates and wide turndown rates, as well as hot, moist or dirty gas conditions, MT100 Series devices are available with two to eight flowrate-sensing points. Multiple sensors are inserted at various depths within a pipe or duct, and their outputs are multiplexed and averaged to produce the flowrate within the process line. The meters can measure flowrates over a wide range with 100:1 turndown, and with accuracy of±0.75% of reading,±0.5% of full scale. They are also dual-function and can provide temperature measurement capability from –50 to 850°F, with accuracy of±2°F. — Fluid Components International, LLC (FCI), San Marcos, Calif.
