1. A system for monitoring an electrostatic powder painting process having a conveyor line adaptable for transporting articles to be electrostatically powder painted sequentially through a plurality of zones in the process, the system comprising:

  • a. dispensing powder paint particles from a delivery container through a conduit to an electrostatic powder paint spray gun operable for applying the powder paint particles to the articles in a painting zone;

    b. sensing the weight of the delivery container and powder paint particles therein with scale means and generating a paint weight signal therewith corresponding to the real time weight of the delivery container and powder paint particles therein;

    c. transmitting the paint weight signal from the scale means to computer-monitor means adaptable for displaying the real time weight of the delivery container and powder paint particles therein as a container weight function over a predetermined period of time;

    d. sensing the speed of the conveyor line with speed sensing means and generating a line speed signal therewith corresponding to the real time line speed; and

    e. transmitting the line speed signal from the speed sensing means to computer-monitor means adaptable for displaying the real time line speed as a line speed function over a predetermined period of time.
