When the liquid level coincides with the horizontal line, the device is in a horizontal state.

[0011] Preferably, the second cylindrical cavity is a circular through hole, and the scale lines of the dial on the horizontal plate are arranged in a ring shape at equal intervals along the circumference of the second cylindrical cavity.
