When the pressure difference across the flow control orifice plate exceeds the critical value, the flow rate stops increasing; but will the pressure difference between the orifices continue to rise?

When the pressure difference across the flow control orifice plate exceeds the critical value, the flow rate stops increasing; but will the pressure difference between the orifices continue to rise?
No. As the pressure difference increases, the flow rate will increase, in my opinion...
When a choked flow occurs, the flow rate does not increase as the pressure difference increases.
With the pipe resistance remaining constant, the flow rate increases as the pressure difference increases; I think in the situation you mentioned, the pressure difference shouldn’t increase
Can it be understood that the pressure difference can change, while the flow velocity through the orifice plate remains constant, causing the total flow rate to change?
The pressure difference is fixed. Determined by the upstream and downstream systems, rather than the flow restriction orifice plate
