WebW = r · Q, which means that the mass flow of fluid passing through a flowmeter (A) is equal to the fluid density (r) times the volume of the fluid (Q). Volumetric flowmeters directly measure the volume of fluid (Q) passing through the flowmeter. The only flowmeter technology that measures volume directly is the positive displacement flowmeter. WebJul 2, 2024 · A mass flow controller is a tool to gauge and control the flow of liquids and gases in the system. A mass controller is a favored option for most measurements as it is not altered by stress and fluid state. This strength gives is it liking industries for accurate readings despite fluid state changes.
