Thermal mass flow meters head into outer space. They replace NASA's outdated technology for maintaining positive space shuttle cargo door air flow on re-entry.

In part two of this blog series, engineer Scott Rouse discusses the advantages of a capillary thermal flow meter over traditional differential pressure devices. For precise gas flow control, advanced digital flow meters take a direct measurement of mass f

In this first of a two-part blog series, engineer Scott Rouse compares capillary thermal flow meters and other premium mass flow controllers to differential pressure (dP) devices. Although dP meters are still common, they measure volumetric flow not mass

Advanced digital mass flow meters offer more flexibility and options that traditional analog flow meters. However, according to Sierra Instruments engineer Paul de Waal, this flexibility also means many communication variables. If you have a complex mass

At Sierra Instruments, we love to tackle tough flow meter applications. In this latest blog post from Mark Blackbourn, learn how a capillary thermal mass flow controller that's designed to measure gas can be used to control liquids, too.
