Elveflow Software ESI - Pressure-driven flow control demo

Elveflow’s dedicated software interface, built to make experimenter’s life better.It is perfectly adapted for the control of simple and advanced setups and workflow automation. It integrates several modules that make time-consuming and painful tasks so simple. It comes with SDK libraries to control Elveflow system from your own code.

The OB1 control window allows to:
- Visualize the key parameters of each channel:
the command pressure, the output pressure
- Visualize sensor output when one is connected to the OB1 (a flow rate sensor on the first channel in the screenshot presented below)
- Set any pressure or flow rate pattern (predefined or custom)
- Easily switch in flow rate control mode (sensor mode)
- Use the pause/play button to preset the parameters on each channel and launch them simultaneously
- Save configurations to gain time in the future or automate your workflow thanks to the sequencer
- Open a graph to visualize and save data
- Launch and use dedicated modules to simplify specific experimental tasks

More detail:
In feedback control mode (“Sensor” mode), you can set a target flow rate, and the inlet pressure will automatically adapt to reach it. The feedback loop relies on a PID algorithm. The D parameter is preset but the gain parameter (P) and the integration parameter (I) can be tuned. We advise you to use the “PI Basic” algorithm that will work for most applications. The user can use the autotune module to automatically find P and I parameters, or set these parameters manually to better match the requirements in terms of responsiveness and stability.
