Abstract:
1. A viscous fluid dispensing system for accurately dispensing viscous fluid and controlling a dispensing operation, the system comprising: a viscous fluid dispenser including an inlet and an outlet, the dispenser being operable to start and stop the flow of the viscous fluid from the outlet onto a substrate; a viscous fluid supply container adapted to hold the viscous fluid, and having an outlet coupled in fluid communication with the inlet of the viscous fluid dispenser to establish a flow path for the viscous fluid between the viscous fluid supply container and the outlet of the viscous fluid dispenser, the viscous fluid supply container further including an pneumatic input adapted to receive pressurized air for forcing the viscous fluid from the outlet of the container; an electronic flow meter device operatively coupled in the pneumatic input of the container to produce electrical output signals proportional to the flow rate of the pressurized air received through the pneumatic input when the fluid is being dispensed from the outlet; and a control operatively coupled to the electronic flow meter for continuously receiving and processing the electrical output signals and performing a responsive control function in a closed loop manner.
