Abstract:
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.
Abstract:
A platform leveling system for an aircraft cargo loader comprises first and second hydraulic cylinders for lifting and lowering corresponding first and second sides of the platform, at least one sensor for generating signals representative of the height of the first side relative to the height of the second side, and a controller for controlling the flow of hydraulic fluid to and from the first and second cylinders in response to the signals generated by the at least one sensor in order to maintain the first and second sides level.
