Thermal mass flow meter QuadraTherm® 780i

Coriolismassfor air

Eliminate drift with DrySense sensor Reduce straight-run requirements with built-in flow conditioning Needs only 1-diameter up and zero downstream diameters Validate in the field for easy in-situ calibration Backed by lifetime sensor warranty The QuadraTherm® 780i is the most accurate inline thermal mass flow meter for air/gas flow rate measurement on the market today, achieving gas mass flow rate accuracy never before possible, +/- 0.5% of reading above 50% of full scale. The QuadraTherm instruments rivals accuracies of Coriolis technology for measuring mass air flow rate with a breakthrough thermal dispersion technology achieving “percent of reading” accuracy. Change Gas Mixtures in the Field-No Recalibration Needed QuadraTherm thermal flow meter equipment comes with on board qMix(tm) gas mixing software that 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 frequently changes. Sierra’s new breakthrough QuadraTherm® qMix RealTime Flare Measurement System (FMS) delivers real-time flare gas flow measurement to accurately measure flows down to 0.1 fps, meeting the full range of EPA regulations. Boiler MACT Certified QuadraTherm air flow measurement devices, such as this thermal mass meter, are 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).
