器をはかり上にのせ、その重量を計測することにより残
存量を確認する方法などが知られている。Conventionally, this type of confirmation method involves placing a pair of electric currents inside the container.
There are two known methods: one in which the liquid level is detected by inserting it into the container, and the other in which the remaining amount is confirmed by placing the container on a scale and measuring its weight.
しかしながら、上記従来のｍ認方法にあっては、前者の
場合には、容器が多数ある場合、各容器毎に電極を一対

題を有していた。However, in the above conventional m-certification method, in the former case, if there are a large number of containers, it is necessary to prepare one pair of electrodes for each container, which increases the number of parts and increases cost. There is a risk that the electrode may dissolve in the liquid in the container and change the quality of the liquid, and in the latter case, it is necessary to place the container on and off the scale one by one, making the device complicated and cumbersome. Additionally, there is a problem in that accurate weighing cannot be performed unless a scale is set for each container.
この発明は、かかる現状に鑑み創案されたものであって
、その目的とするところは、極めて容易かつ正確に容器

It is designed to be checked.
