Abstract

PURPOSE:To accurately control flow volume of solution from a solution containing vessel for a long time by connecting a transparent cylinder to the vessel and controlling a very small flow of solution by a lifting speed of bubble discharged in the transparent cylinder. CONSTITUTION:A pump 30 is driven to equalize negative pressure inside a flow tube 31 and negative pressure inside a container 9 and then an air cock 13 is closed and a flow cock 16 is opened. Then, although solution inside the container 9 starts to flow out, solution cannot flow out since negative pressure in the flow side of the flow cock, namely a flow pipe 23 and negative pressure inside the container 9 are same. Afterward, when an air valve 2 is properly opened to suck in air via an air filter 1, air which has come out from a discharge port 8 into fluid inside a transparent cylinder 4 through a pipe 7 is lifted as bubble. Corresponding to the lifting speed of this bubble, solution flows out from the container 9. As the result, flow of solution can be perceived by watching a transparent pipe 25.
