level

Device for establishing a horizontal plane. It consists of a small, sealed glass tube containing liquid and an air bubble; the tube is fixed horizontally in a block or frame with a smooth lower surface.

The glass tube is slightly bowed, and the level's sensitivity is proportional to the radius of curvature.
