Abstract
The system provides continuous compensation of dispensed volume in a pressure regulated flow control system to compensate for changes in material viscosity and component wear. Two counters are preset with a predetermined value. The first counter is decremented by pulses from a flowmeter on the outlet of the system while the second counter is decremented according to the input command. When the first counter reaches zero, the contents of the second counter are examined and the gain increased or decreased accordingly.
