Achieve high accuracy +/- 0.75% of reading Eliminate drift with patented DrySense™ sensor Validate in the field for easy in-situ calibration Use qMix software to easily change gas composition in the field and retain accuracy Download Flare Gas Mass Measuring Tech Note Backed by lifetime sensor warranty Boiler MACT certified for area source boilers (40 CFR 63, subpart JJJJJJ) and for major source boilers (40 CFR 63, subpart DDDDD) Overview The QuadraTherm® 640i is the most accurate insertion-probe thermal mass flow meter for air / gas mass flow rate measurement on the market today, achieving gas mass flow rate accuracy never before possible, +/- 0.75% of reading above 50% of full scale. The QuadraTherm 640i air / gas mass flow meter marks an accuracy breakthrough in thermal dispersion technology achieving extreme precision with "percent of reading" accuracy, which for the first time rivals accuracies of Coriolis technology for measuring mass air flow rate and other gases. Each QuadraTherm thermal flow meter comes with onboard qMix(tm) gas mixing software which allows you to create custom gas mixtures in the field to compensate for gas compositional changes-no costly recalibration needed. Perfect for managing changes in flare gas composition in the field for upstream oil & gas flare gas measuring applications and other applications in which gas composition fequently changes. The QuadraTherm thermal mass flow meter is also ideal for compliance for Boiler MACT regulations for inlet fuel measurements for area source boilers (40 CFR 63, subpart JJJJJJ) and for major source boilers (40 CFR 63, subpart DDDDD) Patented breakthrough "quad" 4-sensor thermal sensor technology
