Water level (device), the Glossary

A water level (Aλφαδολάστιχο or (υδροστάθμη)) is a siphon utilizing two or more parts of the liquid water surface to establish a local horizontal line or plane of reference.^[1]

Antifreeze

An antifreeze is an additive which lowers the freezing point of a water-based liquid.

See Water level (device) and Antifreeze

Communicating vessels or communicating vases are a set of containers containing a homogeneous fluid and connected sufficiently far below the top of the liquid: when the liquid settles, it balances out to the same level in all of the containers regardless of the shape and volume of the containers.

See Water level (device) and Communicating vessels

Datum reference

A datum reference or just datum (plural: datumsThe plural of this sense of the word datum is datums by convention, in contrast with the other senses of the word in which data usually serves as both the plural form and the mass noun counterpart.)) is some important part of an object—such as a point, line, plane, hole, set of holes, or pair of surfaces—that serves as a reference in defining the geometry of the object and (often) in measuring aspects of the actual geometry to assess how closely they match with the nominal value, which may be an ideal, standard, average, or desired value.

See Water level (device) and Datum reference

Detergent

A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions.

See Water level (device) and Detergent

Dishwashing liquid

Dishwashing liquid (or washing-up liquid in British English), or dishwashing soap, dish detergent, and dish soap is a detergent assisting in dishwashing.

See Water level (device) and Dishwashing liquid

Dye

A dye is a colored substance that chemically bonds to the substrate to which it is being applied.

See Water level (device) and Dye

Elevation

The elevation of a geographic ''location'' is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum). Water level (device) and elevation are vertical position.

See Water level (device) and Elevation

Error

An error (from the Latin, meaning 'to wander'Oxford English Dictionary, s.v. “error (n.), Etymology,” September 2023,.) is an inaccurate or incorrect action, thought, or judgement.

See Water level (device) and Error

Geodesy

Geodesy or geodetics is the science of measuring and representing the geometry, gravity, and spatial orientation of the Earth in temporally varying 3D.

See Water level (device) and Geodesy

Grade (slope)

The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal.

See Water level (device) and Grade (slope)

Hydrostatic equilibrium

In fluid mechanics, hydrostatic equilibrium (hydrostatic balance, hydrostasy) is the condition of a fluid or plastic solid at rest, which occurs when external forces, such as gravity, are balanced by a pressure-gradient force.

See Water level (device) and Hydrostatic equilibrium

Laser level

In surveying and construction, the laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. Water level (device) and laser level are construction equipment and construction surveying.

See Water level (device) and Laser level

Levelling

Levelling or leveling (American English; see spelling differences) is a branch of surveying, the object of which is to establish or verify or measure the height of specified points relative to a datum. Water level (device) and Levelling are vertical position.

See Water level (device) and Levelling

Line of sight

The line of sight, also known as visual axis or sightline (also sight line), is an imaginary line between a viewer/observer/spectator's eye(s) and a subject of interest, or their relative direction.

See Water level (device) and Line of sight

Low technology

Low technology (low tech; adjective forms: low-technology, low-tech, lo-tech) is simple technology, as opposed to high technology.

See Water level (device) and Low technology

Meniscus (liquid)

In physics (particularly fluid statics), the meniscus (menisci) is the curve in the upper surface of a liquid close to the surface of the container or another object, produced by surface tension.

See Water level (device) and Meniscus (liquid)

Siphon

A siphon (also spelled syphon) is any of a wide variety of devices that involve the flow of liquids through tubes.

See Water level (device) and Siphon

Spirit level

A spirit level, bubble level, or simply a level, is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). Water level (device) and spirit level are Inclinometers.

See Water level (device) and Spirit level

Surface tension

Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible.

See Water level (device) and Surface tension

Surfactant

Surfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid.

See Water level (device) and Surfactant

Surveying

Surveying or land surveying is the technique, profession, art, and science of determining the terrestrial two-dimensional or three-dimensional positions of points and the distances and angles between them.

See Water level (device) and Surveying

Vertical and horizontal

In astronomy, geography, and related sciences and contexts, a direction or plane passing by a given point is said to be vertical if it contains the local gravity direction at that point.

See Water level (device) and Vertical and horizontal

Water

Water is an inorganic compound with the chemical formula.

See Water level (device) and Water

Water level

Water level, also known as gauge height or stage, is the elevation of the free surface of a sea, stream, lake or reservoir relative to a specified vertical datum. Water level (device) and Water level are vertical position.

See Water level (device) and Water level
