CONSTITUTION:A feeding pipe 2 having an opening/closing valve 10 is connected with a storage container 1, and a mechanical type measuring device 5 is installed on a loading board 4 for transport. A portable container 3 is placed on the measuring device 5, and the container weight and container charging quantity can be measured. A measurement pointer 21 and a setting pointer 22 are installed at the display part 6 of the measuring device, and when the measured weight accords with the set weight, a detection signal is inputted into a controller 7. Liquid nitrogen, etc., are poured from the feeding pipe device 2, and when the measured weight reaches the set weight, the opening/closing valve 10 is closed by the controller 7, and the charge of a specified quantity of liquid can be carried out surely and automatically.</p> |
