Title: Level gage
Inventor: ISHII MITSUJI
IPC: G01C9/22
Filed: 1981-03-24
Abstract: PURPOSE:To obtain the simple, accurate device by which a horizontal surface can be measured by one time, by bending each end part of a communicating pipe upward, filling the communicating pipe with liquid, and forming a vacuum part at each end part. CONSTITUTION:Each end part of the communicating pipe is bent upward, and the communicating pipe is filled up with the liquid. The vacuum part is formed at each end part of the communicating pipe. For example the end parts 2 of the straight communicating pipe 1 are bent upward in the same directions at approximately 90 degrees, and a horizontal reference line 3 is marked. The communicating pipe is filled up with the liquid 5 such as alcohol so that only a required sapece at the end part 2 becomes a vacuum 2, and the pipe is hermetically sealed. In the case the levels of all the directions of a flat body are simultaneously measured, the communicating pipe is formed in a Y shape or a cross shape. Then the main body of the communicating pipe is placed on the surface of the material to be measured. The sloping direction and the sloping angle of the surface of the material to be measured are detected based on whether the liquid levels at the end parts 2 are higher or lower than the reference line or whether one of the end parts of the communicating pipe is lower or not.
