MT100 multipoint flue gas flowmeters with thermal dispersion flow sensing have earned TÜV certification for AMS/QAL1 continuous emissions monitoring (CEMS), and comply with EN15267-3 with QAL1 and EN14181(2015). MT100 uses one to eight flow-rate sensing points, and can measure hot, moist, aggressive and dirty flue gases up to 454 °C (850 °F), and measure flow rates over a wide range from 0.07 to 305 NMPS (0.25 to 1,000 SFPS) with 100:1 turndown and with accuracy of ±1.75% of reading and ±0.5% of full scale.
