<p>PURPOSE:To prevent a gas cylinder from being charged due to input error by directly registering individual data of the cylinder while inputting them in an arithmetic processing unit through an explosion-proof input means installed in a gas charging place. CONSTITUTION:When a new cylinder needing new registration or an old one needing change of registration is sent into a charging place 1, this cylinder 12 is placed on the weighing base 11 of a weighing machine 6 and thus a registering work begins. Data regarding the cylinder 12, such as a type, a rated charging volume, a tare weight, a manufacturing data, an expiration date of charge, are input from a keyboard 15 by operator's manual operation and sent to a computer 8. The cylinder 12, after registration of its individual data, is placed on a liquefied gas charging machine 5 and charged with a specified volume of liquefied gas on the basis of the registered individual data sent from the computer 8.</p> |
