Abstract
A control system selectively operates an agitator within a main hopper or bulk tank for a product-on-demand delivery system. A differential pressure switch is used to control operation of the agitator. The differential pressure switch measures the pressure difference between the pressurized air pressure upstream of the tank and tank air pressure to determine when the system is not delivering adequate product to the application units, based on the high air flow rate in the system. When the sensor signals that the system is not delivering adequate product, the system automatically starts the agitator, and conversely when the sensor signals that the system is delivering adequate product, the system automatically stops the agitator.
