Dear Samuel,
If you see the example concerning the use of PID, you will see that the
PID output 1 ('control signal') is defined as an energy (in kJ/hr) used
to heat or cool the building. So I think that you have to adapt the PID
output with an equation to obtain a fluid flow rate.
I think that tPiD only give the energy rate necessary to maintain the
controled variable at the setpoint.
Maybe you can have a look at this example in "feedback control" to see
how are used PID.
I am not really sure of what I say, so if someone is able to confirm or
to cancel what I said, he's welcome...
Best regards,
Adrien
