QuadraTherm® 640i Air Mass Flow Meter


Industry's Most Accurate Gas Thermal Insertion Mass Flow Meters

The QuadraTherm® 640i is the most accurate insertion-probe thermal mass flow meter for 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 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 gas mass flow rate.
