Abstract
The invention relates generally to a peristaltic precision metering device, system and method of using the same. Disclosed is a metering device which includes a metering element that can engage with a compressible material line, wherein the metering device can place a selectable peristaltic effect upon the material in the line. Also disclosed is a metering system comprised of a metering device similar to above and a control system attached to the metering element and a robotic positioning system also attached to the metering device. Finally disclosed is a method of precision material dispensing comprised of providing a metering element and base, positioning a compressible material line between the metering element and base, moving one of the base, metering element, material line, or combination thereof, thereby causing a peristaltic effect upon material in the line, and dispensing a precise unit of material from the device.
