Mass Flow Controller
A mass flow controller (MFC) comes into action when we need to measure and control the flow of liquids and gases at a particular range of flow rates. The MFC is usually operated at 10% to 90% for best accuracy. MFC exists in 2 types: Analog and Digital. These 2 types of MFC differ in their ability to control fluids. A digital flow controller controls more than one type of fluid while an analogue controller is limited to the fluid for which it was calibrated.
