Syringe meter

摘要

A syringe meter is provided, including a supply tank, a container with variable capacity, a transmission set, an air supply tube, a liquid outlet tube, and a plurality of valve elements; wherein the container being a bellows tube having two ends sealed; the supply tank having a cyclic tube and a pump connected to bellows tube so that a liquid able to circulate in supply tank and bellows tube; the transmission set being for compressing or pull bellows tube; the air supply tube and the liquid outlet tube being connected to the container; and the plurality of valve elements being disposed at the positions where tubes connected to bellows tube. As such, the capacity of the bellows tube is adjusted for outputting a preset volume, or the transmission set is activated to compress or pull the bellows tube after filling with a liquid to control the output volume.
