A water level is a device used for matching elevations of locations that are too far apart for a spirit level to span. The simplest water level is a section of clear tubing, partially filled with water. Water is easily procured for use, and easily discarded after use. The ends are held vertical, and the rest of the tubing lies on the ground or floor. The water level at each end of the tube will be at the same elevation, whether the two ends are adjacent or far apart. Water levels have been used for many years. The water level is lower-tech than the laser level, but it can be more accurate over long distances. To avoid error, all of the water should be at the same temperature. Other sources of error include difficulty reading due to meniscus.
If the water level is used often, dye can be added to the water to make it easier to see. If the water level is used outdoors in winter, antifreeze can be added to the water.

Famous quotes containing the words level and/or water:
“Alle fresh the level pasture lay,
And not a shadowe mote by seene,
Save where full fyve good miles away
The steeple towered from out the greene,”

“It is so manifestly incompatible with those precautions for our peace and safety, which all the great powers habitually observe and enforce in matters affecting them, that a shorter water way between our eastern and western seaboards should be dominated by any European government, that we may confidently expect that such a purpose will not be entertained by any friendly power.”
—Benjamin Harrison (18331901)
