DOWNLOADThe August 2013 issue of Flow Control magazine featured an article titled “The History and Evolution of Thermal Flowmeters” (pages 22–26), which examined the origins of thermal flowmeters in the 1970s, based on in-person interviews with the founders of Sierra Instruments, Fluid Components Int’l , and Kurz Instruments. Anyone who follows the flowmeter business is likely to know that many mass flow controllers (MFCs) also employ thermal technology. Should these devices also be included in any discussion of the history of thermal flowmeters, or should they be treated separately?
