Thermal Mass Flowmeter

QuadraTherm introduced the first four-sensor thermal mass flowmeter design—three precision platinum temperature sensors and one patented DrySense mass velocity sensor backed by a lifetime warranty. The flowmeter is available in an insertion version and an inline version. The QuadraTherm 780i inline version achieves accuracy of +/- 0.5% of reading making it the most accurate thermal meter in the world (verified by an independent NIST- and NVLAP-accredited metrology laboratory). QuadraTherm measures all thermal heat transfers occurring and works in harmony with our proprietary qTherm algorithm set to solve the First Law of Thermodynamics (for thermal dispersion technology) in a fraction of a second for each mass flow data point.
