New QuadraTherm premium flow sensor features iTherm gas library for instantly calculating thermodynamic and transport properties of every gas or gas mixture.

Most accurate flow sensor in the world, Sierra's QuadraTherm and its 4-sensor technology features iTherm, a living, learning algorithm set and gas library.

Groundbreaking new thermal mass flow meter contains four flow sensors corrects for heat lost to the outside environment due to stem conduction.

New, ultimate thermal mass flow meter with four sensors eliminates unwanted heat-transfer components, a major causes of false flow readings.

A thermal mass flowmeter of unparalleled accuracy, the QuadraTherm measures within +/- 0.5% of reading. Functions in fraction of a second for each mass flow data point.
