These vials are filled, incompletely, with a liquid – usually a <a href="/wiki/Tincture" title="Tincture">colored</a> <a href="/wiki/Aqua_vitae" title="Aqua vitae">spirit</a> or <a href="/wiki/Ethanol" title="Ethanol">alcohol</a> – leaving a <a href="/wiki/Liquid_bubble" class="mw-redirect" title="Liquid bubble">bubble</a> in the tube. They have a slight upward curve, so that the bubble naturally rests in the center, the highest point. At slight inclinations the bubble travels away from the marked center position. 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. </p><p>Alcohols such as <a href="/wiki/Ethanol" title="Ethanol">ethanol</a> are often used rather than water. Alcohols have low <a href="/wiki/Viscosity" title="Viscosity">viscosity</a> and <a href="/wiki/Surface_tension" title="Surface tension">surface tension</a>, which allows the bubble to travel the tube quickly and settle accurately with minimal interference from the glass surface. Alcohols also have a much wider liquid temperature range, and will not break the vial as water could due to ice expansion.

The level is placed on a flat and roughly level surface and the reading on the bubble tube is noted. 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 spirit level is then rotated through 180 degrees in the horizontal plane, and another reading is noted. If the level is accurate, it will indicate the same orientation with respect to the horizontal plane. A difference implies that the level is inaccurate. </p><p>Adjustment of the spirit level is performed by successively rotating the level and moving the bubble tube within its housing to take up roughly half of the discrepancy, until the magnitude of the reading remains constant when the level is flipped. </p><p>A similar procedure is applied to more sophisticated instruments such as a surveyor's <a href="/wiki/Optical_level" class="mw-redirect" title="Optical level">optical level</a> or a <a href="/wiki/Theodolite" title="Theodolite">theodolite</a> and is a matter of course each time the instrument is set up.

The sensitivity of a level is given as the change of angle or gradient required to move the bubble by unit distance. If the bubble housing has graduated divisions, then the sensitivity is the angle or gradient change that moves the bubble by one of these divisions. 2 mm (0.079 in) is the usual spacing for graduations; on a surveyor's level, the bubble will move 2 mm (0.079 in) when the vial is tilted about 0.005 degree. For a precision machinist level with 2 mm (0.079 in) divisions, when the vial is tilted one division, the level will change 0.04 mm (0.0016 in) one meter from the pivot point, referred to by machinists as 5 tenths per foot. This terminology is unique to machinists and indicates a length of 5 tenths <i>of</i> 1 thousandth of an inch.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Types">Types</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Spirit_level&action=edit&section=5" title="Edit section: Types"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:US_Navy_080606-N-9623R-414_Builder_2nd_Class_Kathryn_Henderson,_assigned_to_Naval_Mobile_Construction_Battalion_(NMCB)_3,_uses_a_horizontal_level_and_tape_measure.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/8/8e/US_Navy_080606-N-9623R-414_Builder_2nd_Class_Kathryn_Henderson%2C_assigned_to_Naval_Mobile_Construction_Battalion_%28NMCB%29_3%2C_uses_a_horizontal_level_and_tape_measure.jpg/220px-thumbnail.jpg" decoding="async" width="220" height="147" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/8/8e/US_Navy_080606-N-9623R-414_Builder_2nd_Class_Kathryn_Henderson%2C_assigned_to_Naval_Mobile_Construction_Battalion_%28NMCB%29_3%2C_uses_a_horizontal_level_and_tape_measure.jpg/330px-thumbnail.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/8/8e/US_Navy_080606-N-9623R-414_Builder_2nd_Class_Kathryn_Henderson%2C_assigned_to_Naval_Mobile_Construction_Battalion_%28NMCB%29_3%2C_uses_a_horizontal_level_and_tape_measure.jpg/440px-thumbnail.jpg 2x" data-file-width="3000" data-file-height="2000" /></a><figcaption>Level tool being used to establish horizontality.</figcaption></figure> <p>There are different types of spirit levels for different uses: </p> <ul><li>Carpenter's level (either wood, aluminium or composite materials)</li> <li>Mason's level</li> <li>Torpedo level <figure class="mw-default-size mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:Tool-level.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/f/f7/Tool-level.jpg/220px-Tool-level.jpg" decoding="async" width="220" height="78" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/f/f7/Tool-level.jpg/330px-Tool-level.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/f/f7/Tool-level.jpg/440px-Tool-level.jpg 2x" data-file-width="2950" data-file-height="1050" /></a><figcaption>Torpedo level</figcaption></figure></li> <li>Post level</li> <li>Line level</li> <li>Engineer's precision level</li> <li>Electronic level</li> <li><a href="/wiki/Inclinometer" title="Inclinometer">Inclinometer</a></li> <li>Slip or Skid Indicator</li> <li><a href="/wiki/Bull%27s_eye_level" title="Bull's eye level">Bull's eye level</a></li></ul> <p>A spirit level is usually found on the head of <a href="/wiki/Combination_square" title="Combination square">combination squares</a>. </p> <div class="mw-heading mw-heading3"><h3 id="Carpenter's_level"><span id="Carpenter.27s_level"></span>Carpenter's level</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Spirit_level&action=edit&section=6" title="Edit section: Carpenter's level"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:ButlerTypeC_SpecialLowSensitivity_1995.JPG" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/d/da/ButlerTypeC_SpecialLowSensitivity_1995.JPG/220px-ButlerTypeC_SpecialLowSensitivity_1995.JPG" decoding="async" width="220" height="165" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/d/da/ButlerTypeC_SpecialLowSensitivity_1995.JPG/330px-ButlerTypeC_SpecialLowSensitivity_1995.JPG 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/d/da/ButlerTypeC_SpecialLowSensitivity_1995.JPG/440px-ButlerTypeC_SpecialLowSensitivity_1995.JPG 2x" data-file-width="3264" data-file-height="2448" /></a><figcaption>Carpenter's bulls-eye level</figcaption></figure> <p>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.

The industry practitioners often refer to those levelling tools as a "construction level", "heavy duty level", "inclinometer", or "protractor". These modern electronic levels are capable of displaying precise numeric angles within 360° with 0.1° to 0.05° accuracy, can be read from a distance with clarity, and are affordably priced due to mass adoption. They provide features that traditional levels are unable to match. Typically, these features enable steel beam frames under construction to be precisely aligned and levelled to the required orientation, which is vital to ensure the stability, strength and rigidity of steel structures on sites. Digital levels, embedded with angular MEMS technology effectively improve productivity and quality of many modern civil structures.
