Abstract
A novel enhanced flow metering device is disclosed, as well as related methods, that safely controls and meters the flow of a flow material. A pump fills a flow metering device with a flow material, which then dispenses the flow material to a target. The flow material charges the device by moving into at least one chamber when an actuation shaft is in a charging position. Flow materials are dispensed from the chambers of the flow metering device when the actuation shaft is moved into at least one dispensing positions.
