How to select a Flow Meter?

  1. Need to know the five basic things about the application:
  • What is the fluid?
  • What is the min/max flow rate?
  • What is the line pressure?
  • What is the pressure and temperature?
  • What is the line size


  • 2. In some circumstance, we may also need to know the following:
  • Viscosity
  • Specific gravity
  • Solid content
  • Special materials of construction


 3. We’ll also need to know what you want the flow meter to do

  • Indicate flow Rate
  • Totalize(Resettable and/or non-resettable)
  • Signal outputs(Including pulse and 4-20mA, RS485, etc)
  • Batch control
  • Accuracy demand


 4. Which type flow meter do you prefer to

  • Magnetic flow meter
  •        Main power or battery type
  •        Inline or Insertion
  • Clamp-on Ultrasonic flow meter
  • In-line Ultrasonic flow meter (main power or battery type)
  • Coriolis mass flow meter
