PURPOSE:To obtain a specified weight of liquid quickly and accurately, by supplying a liquid first with a valve for rough-quantity discharge and, then, by a trace quantity with a valve for trace-quantity discharge to measure the specified weight of the liquid. CONSTITUTION:A plurality of supply piping sections 5 and 6 from a liquid supply source 1 are set inside a container 21 placed on a measuring section 23 of a weight measuring device 22 and valves 10 and 9 for rough- and trace- quantity discharge are interposed thereon. Then, first, a liquid is supplied quickly to the vicinity of a specified weight at rough-trace quantity discharge switching point preset with the valve 10 and then with the valve 9 by a trace quantity to the specified weight from the switching point. This process enables weighing quickly and accurately.
