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.

In a pinch, Stanford researcher David Mucciarone decides to take a Sierra flowmeter with him to Antarctica and learns how rugged the controller turns out to be.

Gas composition does not have to affect thermal flowmeter measurements of natural gas energy. Use a sensor that is very sensitive to energy content for precision.
