A juice processing system includes at least one fluid line for a concentrated pulp stream, and a flow restrictor coupled in fluid communication with the at least one fluid line for generating a pressure drop in the concentrated pulp stream indicative of a concentration of pulp therein. The system may further include at least one pressure sensor associated with the flow restrictor for sensing the pressure drop, and a controller coupled to the at least one pressure sensor for generating at least one control signal based upon the sensed pressure drop. The control signal may be for an upstream and/or a downstream control device.
