There are two widely used methods of operation when considering Flow Meters: Mass Flow Meters measure the mass flow rate; and Volumetric Flow Meters measure the Volumetric Flow Rate. But what does THAT mean? In this video we'll break down what is Mass Flow and what is Volumetric flow and which flow measurement method is best for your application.
