Abstract: A fluid injection system includes a fluid injector assembly; a fluid conditioning module having an outlet port that is fluidly coupled to an inlet port of the fluid injector assembly; an injector assembly outlet conduit fluidly coupled to an outlet port of the fluid injector assembly and disposed downstream of the fluid injector assembly, the injector assembly outlet conduit defining a pressure measurement port and a flow-restricting orifice, the pressure measurement port being disposed upstream of the flow-restricting orifice along the direction of fluid flow through the fluid injector assembly; a pressure sensor fluidly coupled to the pressure measurement port; and a controller operatively coupled to the fluid conditioning module and the pressure sensor. The controller is configured to adjust a flowrate of a fluid through the injector assembly inlet conduit based on a pressure signal from the pressure sensor.
