Rotameter Flowmeter Selection

The key questions which need to be answered before selecting a rotameter are:

  • What is the minimum and maximum flow rate for the flow meter?

  • What is the minimum and maximum process temperature?

  • What is the size of the pipe?

  • Would you like a direct reading rotameter or is a look up table acceptable?

  • What accuracy do you need?

  • Do you require a valve to regulate the flow?

  • Will there be back pressure?

  • What is the maximum process pressure?
