Types of Level

-has a long telescope attached to the level bar

- the telescope, which can be rotated 360°, fixes

the direction of the line of sight

- attached to the level bar is the level vial which

always remain in the same vertical plane as

the telescope

- leveling head – supports the telescope and

permits the bubble in the tube to be centered

by means of the leveling screws

• Dumpy Level

• Tilting Level

• Automatic Level

• Wye Level

- a level instrument where most of its metal

parts are made of invar to reduce the effects of

temperature

- employed in first-order leveling work where

extreme precision is an important

requirement

- equipped with stadia hairs and vertical and

horizontal cross hairs which makes it suitable

for three-wire leveling

• Dye Level

• Automatic Level

• Geodetic Level

• Transit as a Level

also called a construction level or architect’s

level

- used primarily in building construction where

a high degree of precision is not a primary

requisite

- horizontal circle – used when measuring or

laying out horizontal angles

• Dumpy Level

• Builder's Level

• Tilting Level

• Hand Level

- has a detachable telescope which rests in  supports

- curved clips – used to fasten the telescope in

place

• Geodetic Level

• Laser Lever

• Tilting Level

• Wye Level

- does not use a level vial and its ability to level

itself depends upon the action of a complex

pendulum-and-prism device

- equipped with a prismatic device called a

compensator which is suspended on fine, non

magnetic wires

• Transit as a Level

• Wye Level

• Automatic Level

• Hand Level

- can be tilted or rotated about its horizontal axis

- tilting knob – used to rotate the telescope into

a correct horizontal position

- employed for very precise leveling operations

and is equipped with a horizontal circle which

makes it suitable for layout and construction

surveys

• Tilting Level

• Dumpy Level

• Geodetic Level

• Laser Level

- hand-held instrument used on surveys

involving short sights

- consists of a brass tube about 15 cm long

having a plain glass objective and a peep sight

eye-piece

• Tilting Level

• Hand Level

• Builder's Level

• Laser Level

- usually attached to conventional surveying

instruments and uses laser light for leveling

work

• Laser Level

• Geodetic Level

• Transit as a Level

• Dumpy Level

- engineer’s transit – universal surveying

instrument

• Laser Level

• Transit as a Level

• Automatic Level

• Builder's Level
