The MicroTrak provides the most accurate measurement of very low-flow gases. Systems integrators/OEMs and lab researchers treat the MicroTrak thermal mass flow controller as a true multi-gas digital ...

This temperature differential is directly proportional to the mass flow measurement. All thermal mass flowmeters work by measuring the cooling effect of a moving gas along a cylinder. The cooling ...

In contrast, thermal mass flowmeters are suitable for direct mass flow measurement of gases, not volumetric flow. Because thermal mass flowmeters count the gas molecules, they are immune to changes in ...

Unaffected by upstream gas temperature and pressure fluctuations ... DIY Calibration: If you prefer to calibrate your own mass flow meters and controllers in-house, Sierra provides all necessary ...

span and full scale independently for each gas. DIY Calibration: If you prefer to calibrate your own mass flow meters and controllers in-house, Sierra provides all necessary software and training ...

Just select a gas from the menu and the controller is ready to go ... DIY calibration: If the users choose to calibrate their own mass flow controllers and meters in-house, Sierra offers all of the ...
