ABSTRACT:
A by-pass control system for a meat injection system has a variable speed pump that transports fluid to a meat injection machine. Excess fluid is transported to a by-pass control valve. The valve has a moveable piston disposed therein that separates the valve into a fluid chamber and an air chamber. The piston moves back and forth based on the relationship between fluid pressure and air pressure. Sensors are disposed within or through the lid or the valve to sense the position of the piston. A controller is connected to the sensors and the variable speed pump and adjusts the speed of the pump based on the position of the piston.
