SYSTEM FOR OUTPUTTING AMOUNT OF LIQUID REMAINING IN CONTAINER

Japanese Patent JP2022171440

A

To provide a system that can sequentially observe and grasp a situation of gradual reduction of liquid.SOLUTION: There is provided a system for outputting the amount of liquid remaining in a container 17, and the system comprises: a measuring plate 21 on which the container is placed; a weight detector 27 that detects the weight of the container placed on the measuring plate 21; signal input units 23, 24; means that acquires a first weight in a state in which an empty container is placed on the measuring plate, in a state in which a weight with the same weight as the weight of the empty container is placed on the measuring plate, or in a situation in which nothing is placed on the measuring plate; means that acquires a second weight W2 of the container filled with a predetermined amount of liquid or a weight with the same weight as that of the container filled with the predetermined amount of liquid in a state in which the container filled with the predetermined amount of liquid or the weight is placed on the measuring plate; means that measures a third weight W3 of the container in which liquid remains after a certain time interval; an arithmetic unit that calculates the remaining amount ratio R of the liquid by using the first to third weights W1 to W3; and an output unit that outputs the remaining amount ratio calculated by the arithmetic unit.SELECTED DRAWING: Figure 2
