This was voltage ratio I was talking about and equation that I used to describe flow of proportional valve. In my model instead of that voltage ratio I use valve openness that I get from my PID regulator which then I scale from 0-100% to 0-1 and send back to model so it scales valve orifice...

Let's say this is the valve in system. https://www.boschrexroth.com/en/xc/products/product-groups/industrial-hydraulics/proportional-high-response-and-servo-valves/proportional-flow-control-valves/proportional-flow-control-valves/3frez there are characteristics of it in pdf. And I modeled valve...

Thank you for such detailed descriptions and your work. Main element of that system should be proportional solenoid valve and its control. So that is type of valve I must use. Valve should be controled by current as it is described where I was modeling system(equation for valve). Those type of...

Tank height and tank base radius is entered through HMI for both of the tanks separately and asumption is that at the start of simulation, tank 1 is full of liquid(water) and tank 2 is empty. I didn't asume piping slope as I mentioned that tanks are aligned and pump and valve are on the same...

Yes, it is discharge pressure of pump and in this case it is same pressure that is valve inlet pressure.
