clinometer

[klə′näm·əd·ər]
(engineering)
A hand-held surveying device for measuring vertical angles; consists of a sighting tube surmounted by a graduated vertical arc with an attached level bubble; used in meteorology to measure cloud height at night, in conjunction with a ceiling light, and in ordnance for boresighting. Also known as Abney level.
A device for measuring the amount of roll aboard ship.

Clinometer

 

a very simple geodetic instrument that is used to measure the slope angles of a terrain. A typical clinometer (see Figure 1) consists of a circular metal casing (1) and a sighting tube (2) that is fastened to the casing. The casing contains a graduated disk (3) on a spindle; attached to the disk is a weight that hangs

plumb, keeping the disk in a constant position. Other forms of clinometers are also available. The precision with which slope angles are determined by means of a clinometer does not exceed 0°.2.

Closed-end curved glass tube filled with a liquid similar to kerosene and enclosing a round glass ball. It may be used as a leveling device or in a turn and slip indicator to indicate the relationship between the force of gravity and centrifugal force in a turn.
