A variant of the linear spirit level is the bull's eye level: a circular, flat-bottomed device with the liquid under a slightly convex glass face with a circle at the center. This reading indicates to what extent the surface is parallel to the horizontal plane, according to the level, which at this stage is of unknown accuracy.

The sensitivity of a level is given as the change of angle or gradient required to move the bubble by unit distance. Alcohols have low viscosity and surface tension, which allows the bubble to travel the tube quickly and settle accurately with minimal interference from the glass surface.

A spirit level, bubble level, or simply a level, is an instrument designed to indicate whether a surface is horizontal (level) or vertical ( plumb). Digital spirit levels are increasingly common in replacing conventional spirit levels, particularly in civil engineering applications such as traditional building construction and steel structure erection, for on-site angle alignment and leveling tasks. Where a spirit level must also be usable upside-down or on its side, the curved constant-diameter tube is replaced by an uncurved barrel-shaped tube with a slightly larger diameter in its middle. The industry practitioners often refer to those levelling tools as a "construction level", "heavy duty level", "inclinometer", or "protractor". Starting from a point with a known elevation and going cross country (successive points being perhaps 100 meters (328ft) apart) height differences can be measured cumulatively over long distances and elevations can be calculated.The spirit level is then rotated through 180 degrees in the horizontal plane, and another reading is noted.

Ground spirit level vials are generally used in applications which require a higher degree of accuracy than is achievable with the lower cost plastic vials. citation needed] It is very likely that these levels were in use in France and elsewhere long before the turn of the century.These vials are incompletely filled with a liquid, usually a colored spirit or alcohol, leaving a bubble in the tube. They have a slight upward curve, so that the bubble naturally rests in the center, the highest point. The level is placed on a flat and roughly level surface and the reading on the bubble tube is noted. This terminology is unique to machinists and indicates a length of 5 tenths of 1 thousandth of an inch.

A similar procedure is applied to more sophisticated instruments such as a surveyor's optical level or a theodolite and is a matter of course each time the instrument is set up. The device was unique in that it could be placed on a machine bed and show tilt on the x-y axes simultaneously, eliminating the need to rotate the level 90 degrees. Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item.A traditional carpenter's spirit level looks like a short plank of wood and often has a wide body to ensure stability, and that the surface is being measured correctly. Digital levels, embedded with angular MEMS technology effectively improve productivity and quality of many modern civil structures.
