ABSTRACT:
Apparatus and techniques for maintaining a constant flow rate of a coating material in a painting system are presented. A test loop is provided in shunt with the conduit passing a coating material in a painting system. The test loop determines a sensitivity factor for the coating, establishing for that coating a relationship between temperature changes and pressure. That sensitivity factor is then used to regulate the pressure at the spray nozzles to compensate for temperature changes experienced in the coating material.
