FIGS. 1 and 2 are schematic diagrams showing the principle of the reaction of the buoyant force of a liquid. In Figure 1, if weights 3°4 of equal mass are hung from both ends of belt 2 which is hung on pulley 1, then
The left and right weights 3 and 4 are balanced with each other and stopped at equal height positions. Now, as shown in Fig. 2, if a be-force 5 containing a predetermined amount of water is prepared and one of the weights 3 is submerged in this be-force 5, the weight 3 will be buoyant due to the water in the be-force 5. As a result, the balance between the weights of both labor unions 3 and 4 is disrupted, and the weight 3 of one of them rises. In the present invention, this buoyancy reaction is used to measure the volume, mass, or density of an object.

Now, as shown in FIG.
A container 8 containing a predetermined amount of water is placed on top, and the other plate 1 is placed on top.
After placing a table 12 having a predetermined weight on 1, one end of a tube 13 such as a glass pipe with a relatively small diameter is placed in water in a container 8, and the other end is closed with a finger 14. By adjusting the amount of water in the container 8, the heights of the left and right pans of the balance 9 are balanced. Next, as shown in FIG. 4, the object to be measured 6 suspended from a stand or the like (not shown) via the hanging tool 7 is completely submerged in the water in the container 8. Then, the object to be measured 6
The container 8 in which the water is immersed becomes heavier due to the reaction of the buoyant force of the water, and the balance 9 tilts. Furthermore, as shown in FIG.
By sequentially placing weights on the balance 9 until it is balanced, accurate measurements can be made up to, for example, 1710 grams. In this case, the following formula is established: buoyant force=displacement amount of the object to be measured 6=volume of the object to be measured 6=reaction of the buoyant force, and from this, the magnitude of the reaction of the buoyant force can be determined. Therefore, if the mass of the object 6 to be measured is N grams, the magnitude of the buoyancy reaction is N grams. Further, the amount of water discharged directly becomes the volume of the object 6 to be measured.

A small object 6 to be measured is floated in water in a container 8, and then, as shown in FIG. 8, a weight is placed on a table 12 and a balance 9 is balanced.
