Claims

[Claims for Utility Model Registration] 1. A transparent or partially transparent vertically elongated container 1 that is provided with a ventilation port 6 at the top and a liquid passage port 5 at the bottom and holds liquid C therein; The container 1 is set so that the level difference can be measured based on the liquid level _C1 of the liquid C.
two sets of measuring containers A 1 and A 2 each comprising a measuring ruler, 2, which is attached in close parallel contact with the measuring container A ₁ , A ₂ ;
Furthermore, by connecting the respective liquid passage ports 5 provided in the two sets of measurement containers A ₁ and A ₂ using a communication pipe B so that the liquid C held in the containers 1 can communicate with each other. , a two-point measuring level that can measure the level difference between two points by applying the principle that the free surface of calm water is horizontal. 2. Utility model registration claim 1, characterized in that the measuring ruler 2 is also used by the vertically long container 1, and a dimension scale 2a is printed or engraved along the vertically long portion of the vertically long container 1. Level as described in section. 3 Using _the communication pipe B ₁ via the control valve ₅₃ , It is configured to be connected to the level setting liquid tank 56 so that the liquid C held in the two sets of measuring containers A ₁ and A ₂ and the liquid C held in the level setting liquid tank 56 can communicate with each other. Therefore, when the control valve 53 is closed, the level difference between two points can be measured;
When 3 is opened, the horizontal liquid level C ₁ formed by the communication between the liquid C held in the two sets of measuring containers A ₁ and A ₂ and the liquid C held in the level setting liquid tank 56 is used as a basic level. The spirit level according to claim 1 or 2, characterized in that it is capable of measuring many reference points. 4 Connect _{the water inlet 5 of any one of the two sets of measurement containers A 1 and A 2} _to _the _water inlet 5 a of the level setting liquid tank 56 through a communication pipe B. The liquid C held in the measuring container _A1 or _A2 and the liquid C held in the level setting liquid tank 56.
4. The spirit level according to claim 1, 2, or 3, wherein measurement of many reference points can be performed by configuring the spirit level so that it communicates with the spirit level.
