PURPOSE:To take out an arbitrary amount with high accuracy by introducing a gas into a conduit in which liquid is flowing, separating these to a gaseous part and a liquid part in this conduit, detecting the flow times of the liquid part obtained by the separation and controlling the taking-out amount of the liquid. CONSTITUTION:With the volume from the solenoid valve 7 of a conduit 6 up to a liquid detector 8 as a unit amount, the liquid in a vessel 1 is led out successively by every unit amount by controlling the solenoid valves 3, 7 with a control circuit 4, whereby the liquid is poured into a beaker 5. It is possible to take out only the required amount of the liquid in the vessel 1 by beforehand setting the unit amount and setting the setting signal P of the liquid take-out amount corresponding to the required liquid amount in the control circuit 4. |
