An Abney level and clinometer is an instrument used in surveying which consists of a fixed sighting tube, a movable spirit level that is connected to a pointing arm, and a protractor scale. An internal mirror allows the user to see the bubble in the level while sighting a distant target.
An inclinometer or clinometer is an instrument used for measuring angles of slope, elevation, or depression of an object with respect to gravity's direction. It is also known as a tilt indicator , tilt sensor , tilt meter , slope alert , slope gauge , gradient meter , gradiometer , level gauge , level meter , declinometer , and pitch & roll ...
A spirit level, bubble level, or simply a level, is an instrument designed to indicate whether a surface is horizontal (level) or vertical . Two basic designs exist: tubular (or linear ) and bull's eye (or circular ).
Modern automatic level in use on a construction site A level is an optical instrument used to establish or verify points in the same horizontal plane in a process known as levelling . It is used in conjunction with a levelling staff to establish the relative height or levels (the vertical separation ) of objects or marks.
An inclinometer contains a ball sealed inside a curved glass tube, which also contains a liquid to act as a damping medium. The original form of the indicator is in effect a spirit level with the tube curved in the opposite direction and a bubble standing in for the ball. [ 5 ]
Plumb bob with scale as an inclinometer Plumb bob with string in masonry work. A plumb bob and line alone can determine only a vertical reference. However, if they are mounted on a suitable scale the instrument may also be used as an inclinometer to measure angles to the vertical.
Sean “Diddy” Combs has been accused in a new lawsuit of dangling a woman from the 17th-floor balcony of an apartment during an altercation. The lawsuit filed in Los Angeles by fashion designer ...
The modern electronic tiltmeter, which is slowly replacing all other forms of tiltmeter, uses a simple bubble level principle, as used in the common carpenter level. [4] As shown in the figure, an arrangement of electrodes senses the exact position of the bubble in the electrolytic solution, to a high degree of precision.
