| description | PROBLEM TO BE SOLVED: To make the cost low by providing 2 levels of pressure control standard and the coefficient of pressure standard fluctuation to control the gas pressure, successively comparing the observation pressure value and coefficient of fluctuation in each point of time with each set value to judge and controlling the start/stop of the feed of the liquefied gas to reduce the feed frequency or the feed quantity of the liquefied gas. SOLUTION: In the case of vaporizing the liquefied gas in a liquefied gas storage tank 2 and feeding to user so as not to make the gas pressure from a liquefied gas production device (air separating device) 1 equal to or below the required min. pressure value in the user, the high and low 2 levels of the pressure control standard value corresponding respectively to the cases of the lowering/increasing of the gas pressure observed by the pressure gauge 9 are setted. And when the observation gas pressure in lowering is between 2 levels of the lowering pressure control standard values and the coefficient of the fluctuation of the gas pressure is compared with the lowering standard coefficient of the fluctuation and is higher than the lowing standard coefficient of the fluctuation, the feed of the liquefied gas is started. On the other hand, if lower, a vaporizing feed valve 3 is controlled so as to start the feed of the liquefied gas after the observation value becomes lower than the low level lowering pressure control standard value. |
