Abstract
Methods and systems of accurately dispensing a viscous fluid onto a substrate. In an embodiment, a method includes using an electronic flow meter device to produce electrical flow meter output signals and performing a responsive control function in a closed loop manner by adjusting at least one dispensing parameter to correct for a difference between an output data set and a reference data set. In another embodiment, a system includes a control operatively coupled to a gas flow meter device and to a weigh scale allowing for a density of an amount of viscous material to be determined. In another embodiment, a method includes using a control coupled to both a gas flow meter device and a weigh scale and performing a responsive control function in a closed loop manner by adjusting at least one dispensing parameter using gas flow meter output signals and weigh scale output signals.
