I have replaced all the tube to black tube so they dont twist like before but the flow is still low. Its only 1.5 L/min. If I run the loop only on the Mora, the flow is 1.5 L/min to 6.5L/m. No idea why its not contant then I connect it to my pc and the flow stays 1.5 L/min . I tried to install 2 more d5 pumps but flow is still low.

Maybe a stupid question, but have you cleaned your blocks that they're not full of gunk or other crap?
 
That memory thing on one module looks very restrictive.

cpu block is new, GPU block is 1 and a half year without cleaning.
 
Whats ID of tubing?
pump rpm what it should be for what you set?

1½yrs without cleaning is pretty long time, there may be crap which is restricting the flow.
 
Are you having temp issues and that's the cause of your concern?

What does the entire loop consist of? Include block model#s, what your using to gather flow data etc... so we can figure out where your restrictive components are located in the loop and if you may be looking at a false positive.

When your coolant enters your reservoir does the flow look normal?
 
temp is fine. just don't know why flow is so low compared to before. I used to have 240 L/h now its like 1.5 L/min. Different flow sensor.

Bad pump
 
So, new flow sensor, flow rate varies... maybe it is the new flow sensor?
