摘要： PURPOSE:To improve the weighing accuracy and to arrange plural pieces of weighing containers by making a cross sectional area of a liquid inlet of the weighing container small, connecting a liquid supplying pipe to this liquid inlet in a state across the inlet and setting a liquid supplying pipe connecting port to a weighing liquid level. CONSTITUTION:After the inside of weighing containers 1, 2 is made vacuum by opening valves 20-22 and driving a vacuum pump 8, each valve is closed. Subsequently, when a liquid is allowed to flow to a liquid supplying pipe 3 from a liquid supplying tank 4 by opening a valve 15, the liquid flows into the container 1 through a liquid inlet 1a in accordance with a head, the container is filled therewith, and subsequently, the container 2 is filled. The surplus liquid overflows to the inside of the pipe 3 from a liquid supplying pipe connecting port 6, and is fed to a collecting tank 5. At this time point, the valve 15 is closed, and when the liquid in the pipe 3 is collected to the inside of the tank 5 by opening a valve 16, the liquid in the containers 1, 2 becomes full up to the liquid level of the connecting port 6, and weighing is executed of itself. Since a cross sectional areas of the inlets 1a, 2a is made small enough, even if swollen height of the liquid in the weighing liquid level is varied, its quantitative error can be made small.
