How Thermal Mass Flow Meter Technology Works

In this video from Sierra, you'll learn the theory and working principles of thermal dispersion mass flow technology that is used in our gas flow meters.

Industrial thermal mass flow meters, also known as thermal dispersion or immersible thermal mass flowmeters, comprise a family of instruments for precision measurement of total mass flow rate equation of a fluid, primarily gases, flowing laminarly through closed conduits such as pipes and ducts. There is a wide diversity in applications for these types of meters, including correction factors, clean energy, flare gas, wastewater aeration, chilling food and fermenting beverages, just to name a few.

Often more economical than other mass flow meters, thermal instruments have become extremely popular due to their ability to measure very low to very high flows with the same instrument. As a leading supplier of thermal meters, Sierra demonstrates the working principles and advantages of how this rugged, reliable, quality calibrated, easy-to-insert and price effective technology works.
