Selecting Variable Area / Rotameter Flow Meters

The main questions which need to be considered before selecting a rotameter or variable area (VA) flow meter:

  • Is the fluid liquid or gas?
  • What is the minimum and maximum working flow range?
  • What is the density of the fluid at the working temperature / pressure?
  • What is the viscosity of the fluid?
  • What accuracy range is required from the flow meter?
  • What is the maximum operating pressure?
  • What is the maximum operating temperature?
