Abstract:
1. A liquefied gas supply system, comprising: a plurality of liquefied gas containers, wherein the gas containers are in fluid connection with each other, each of the containers in fluid connection with each other via piping, the piping connecting the liquefied gas containers with a common gas supply line for transporting gas from the containers; a detector, installed in each of the containers, that detects a volume of liquefied gas contained in each of the containers; a heating device installed on each of the containers; and a control device that processes information obtained by each of the detectors and controls each of the heating devices, wherein, for each of the liquefied gas containers, the control device controls the heating device so that a liquefied gas supply of the liquefied gas supply system is to be consumed uniformly, the control device controlling each of the heating devices based on a value obtained by a comprehensive processing of the information obtained from all of the detectors so that a supply of liquefied gas within each of the containers is consumed uniformly as the liquefied gas of the containers evaporates into output gas to be transmitted through the supply line, wherein each of the detectors comprises a weight detector of the liquefied gas, wherein said value is an average weight obtained by averaging detected weights of the liquefied gas in each of the containers, and wherein said control device controls each of the heating devices so that a difference between a detected weight of one of the containers and the average weight becomes smaller than a predetermined value.
