help me!!!

[flobuc]

Hello everyone!! !
I am a student of mechanical ing and I am doing the thesis for three-year degree!
I'm developing a fluid distribution system. my problem to solve is that I have to send the fluid to a user always at 2 bar, but with variable flow rate. I had thought of solving by putting a flow-meter connected to the pump inverter (controlled by a plc). But now I'd need some more information on this technique, would someone know how to recommend some site or book to learn more?? Thank you very much
:biggrin:

Your very first problem is that you didn't read the rules and that you didn't show up. . .

What a bad solution. . .
What are we talking about? is not a proportional bypass valve better? Isn't it better to nail the pump's work point?

p.s.
the primary problem, even before the rules and presentations, lies in the thread title. Does a "help me" help you understand the extent of the problem? Let us make sure that you find the solution, do you think that in the future someone else with the same problem is helped by this title in finding the discussion?

Is there any moderator from the good soul that renames it?

Sorry everyone, I'm new to the site! I'll try. .
However we talk about low flow rates, the range goes from 0.9 to 1.2 liters per minute.in fact I am using a screw pump, very precise in the adjustments.
I beg your pardon, but a proportional bypass valve provides for an accumulation lung!?

no, the extra fluid returns back to the pump's mandate, which will therefore always be processed the same flow.
