PRECISION GAS FLOW METERS & GAS FLOW CONTROLLERS

What information do we need for selecting and sizing the mass flow meters and controllers?

What information do we need for selecting and sizing the mass flow meters and controllers?

Always provide a description of your application, why and how you want to use the units in your process.
At the very minimum we need the following information:

  • Gas (Specify all components if it is a gas mixture with their %)
  • Maximum and minimum flow and they units (f.i. ln/min or Gr/hr)
  • Pressure at the installation point (Inlet of the flow meter)
  • In case of a Mass flow controller the pressure behind the Mass flow controller (Your process pressure)
  • Minimum and maximum gas and ambient temperature
  • How is the device to be read out/controlled: visually on site / by means of analog signal (please define, e.g. 4-20 mA) / digitally via standard software get-red-y / SPS / client’s own system
  • Position (vertical/Horizontal) and any specific mounting and location information (f.i. required IP rating or Ex certification)
