New QuadaTherm Flow Sensor: with iTherm, It Learns!

Nov 20, 2012

With iTherm, It Learns…

QuadraTherm’s four-sensor technology provides the critical inputs for iTherm’s living, learning algorithm set and gas library to accurately manage changes in gas and pipe selection, gas temperature, gas pressure, and outside temperature.

Our revolutionary thermal mass flow meter with iTherm solves the First Law of Thermodynamics (for Thermal Dispersion Technology) in a fraction of a second for each mass flow data point. It calculates stem conduction and all other unwanted heat loss components, subtracts them out, and then computes the mass flow rate from the remaining forced convection component.

And, with Dial-A-Pipe, it lets you relocate the probe to different pipe sizes and types in the field. With Dial-A-Gas, it provides gas change capability with highly accurate readings.
