Abstract

See full text

An electrostatic spray coating system has a reservoir into which a metered quantity of electrically conductive paint is flowed from a grounded color changer and through a first flow meter. After filling the reservoir, at least a portion of the flow path between the reservoir and the color changer is cleaned of paint to electrically isolate the reservoir and paint therein from the color changer. The paint in the reservoir is then flowed through a second flow meter to an electrostatic spray gun. The second flow meter is electrically isolated from ground and is used to compare the quantity of paint delivered to the spray gun to the quantity of paint loaded into the reservoir, as well as to monitor and control the volume flow rate of paint from the reservoir to the spray gun. The arrangement makes it possible to spray substantially all of the paint flowed into the reservoir and to accurately control the flow rate of paint to the spray gun.
