<p>PURPOSE:To improve workability, by changing an amount of gas to be charged to a flow rate on the basis of a weight of a container measured by a single electronic scale, so as to conduct gas charging. CONSTITUTION:An electronic scale 3 is arranged on a feed line 1, so as to measure a weight of containers 10 fed on the feed line 1 and compute a residual amount of gas in the containers 10. Charging valves 7 and flow meters C1-Cn are provided in supply pipes from a gas distributor 5, so as to compute an amount of gas to be charged, on the basis of flow rate data from the flow meters C1-Cn, and control opening and closing operations of the charging valves 7. With this arrangement, a central processing unit (CPU) may be used, and accordingly a centralized control of a charging work may be achieved, thereby remarkably improving workability.</p> |
