DEVICE AND METHOD FOR PREDICTING LIQUID QUANTITY OF TANK AND DEVICE AND METHOD FOR DETECTING ABNORMALITY IN LIQUID QUANTITY OF TANK

摘要

PROBLEM TO BE SOLVED: To provide a tank liquid quantity prediction device having high prediction accuracy in the case of predicting future liquid quantity from the transition of liquid quantity. SOLUTION: The tank liquid quantity prediction device installed in a process for charging/discharging a solution into/from a tank by batch transfer is provided with a means 10 for inputting a measuring signal of liquid quantity in the tank at prescribed sampling time SMT and predicting and outputting proximate liquid quantity in the tank and a means 20 for determining the interval of the sampling time SMT based on the charging/discharging time of the tank.
