Hi guys,
I need to do the following control:
need to control two parallel streams from a common one. I have 2 flowsensor that control 2 dampers. That's quite easy. But I have the possibility to modify de speed of the upstream pump of the common duct, and I want to adjust it, so that one of the dampers (the most opened) is at 70% (reading the position).
Can this been done easily? Or is it an unstable configuration?

Thanks to all.
