What is the principle of the Flow Rate Control Module (FRCM)?

The FRCM is the solution to control flow-rates within your system. The FRCM uses pressure actuation to control flow-rates. Thanks to this unique algorithm the pressures are adjusted automatically to reach the flow-rate set point.

The process can be divided in 4 steps:

  • Identification step to create the internal model: flow-rate responses to pressure orders are recorded.
  • Flow-rate set points are entered by the user via MAESFLO™ software. The FRCM algorithm automatically computes the pressure orders needed to obtain the flow-rate set points.
  • The computed pressure orders are automatically sent to the pressure actuator (MFCS™-EZ or MFCS™-EX) which quickly applies them to the pressurized reservoirs.
  • The pressure drives the liquids inside the reservoirs through the microsystem. The measured flow-rates are sent back to the FRCM algorithm which compares computed and measured flow-rates. The algorithm automatically adjusts the pressure values to maintain the flow-rate set points. During the experiment the model is continuously computed to check any variation and adapt its response.
