calculations that do not return on load losses

empiricals say that it is usually always the circuit that determines the pressure, while the pump gives the flow; the classic example is the barrel to water the garden: only partially obstruct the output (or change the circuit) and the pressure will rise immediately.

or maybe the flow rate is not 60 lt/min because the maximum valve is opened downstream of the pump, can be many things
 
but does not the pressure also depend on the downward resistance? maybe you have too yielding load and then turn part of the piezometric energy into kinetic energy of the fluid column? in what conditions of use do you find 200 bars instead of 260 waits?
Wait, I don't get this.
if I misjudge pressure and flow into two points of a conduct I must have the same flow (if I have dry feet) and two different pressures. the difference between the pressures depends on the roughness and v^2.
What else?

You're right I missed the double measure, I realized that one data was measured and the other estimated. the pressure of sending the measures downstream of the maximum valve?

downstream of the maximum valve and also of the distributor (see diagram)
 
Okay, trouble solved.
I'm a little ashamed, but the load sensing was limiting the pressure out of the distributor because the load didn't absorb power. It wasn't all load loss.

Whoa, whoa, whoa, whoa, whoa, whoa!

better so you give, at least you have solved
