Introducing the World’s Most Accurate Thermal Mass Flow Meter

Sierra Instruments today introduces their new QuadraTherm™ 640i / 780i Thermal Mass Flow Meter Series, marking a disruptive breakthrough in thermal dispersion technology. With its sensor design advancements, coupled with a proprietary iTherm “Brain”, the 780i inline version achieves gas mass flow rate measurement accuracy of +/- 0.5% of reading above 50% of the full scale (Air) making it the most accurate thermal meter in the industry. Before today, this level of accuracy was never thought possible with thermal dispersion mass flow meters.
