How Thermal Mass Flow Meter Technology Works

In this NEW video from Sierra, you’ll learn the operational principles of thermal dispersion mass flow technology.

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 of a fluid, primarily gases, flowing through closed conduits such as pipes and ducts. There is a wide diversity in applications for these types of meters, including 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 mass flow meters, Sierra demonstrates the principles of operation and how this rugged, reliable, easy-to-insert and economical technology works.
