780i Inline Mass Flow Meter

 Accuracy Never Before Possible!

The QuadraTherm innovation introduces four sensors—three precision platinum temperature sensors and one patented DrySense mass velocity sensor.  For the first time, the result is gas mass flow rate measurement performance rivaling Coriolis, but with 100:1 turndown, low pressure drop, and a much lower price point.  Explore the menu to your right to learn more…
