The MT91 flow meter measures mass flow almost anywhere with variable conditions limit single-point flow meter effectiveness. The MT91’s design combines FCI's highly reliable thermal dispersion, no-moving parts flow element design with up to 16 flow sensing points while operating over a wide temperature range up to 850° F [454° C]. It features a wide turndown range available from 5:1 to 100:1 with a flow range from 0.25 SFPS to 150 SFPS (0,08 NMPS to 46 NMPS) and up to four meters can be installed.
