The invention is related to gages to measure incline angles of moving and immobile objects and can be used in incline angle gages in such transportation vehicles as airplanes and ships (if a phosphorus scale can be applied to a closed loop clear tube) as a standby device to display pitch and roll angles (FIG. 5, FIG. 6, FIG. 7, FIG. 8). The purpose of this invention is an effective measurement of incline angles in stationary and dynamic objects in a wide range (0°-180°, 0°-360°). Faster measurement is required to improve stated parameters of the general purpose liquid angle indicator. It is achieved because liquid, an air bubble or indicating ball within the semicircular and round clear tube, subjected to gravitational forces, can display measured angles relative to the scale on the graduated clear tube without being in a horizontal position.

An instrument for determining level or plumb orientations includes an elongated body having a plurality of orientation measurement devices. Each of the orientation measurement devices can indicate either a level or plumb orientation depending on a position of the instrument. The orientation measurement devices each include a chamber having front and rear convex sides, a fluid contained in the chamber, and an air bubble floating in the fluid. The elongated body includes a set of first openings and a set of second openings. The orientation measurement devices are embedded into the elongated body through the first set of openings and the orientation measurement devices each include bubble therein viewable from the front and back of the elongated body. The bubble is also viewable from the top and bottom of the elongated body through the second set of openings.

Described implementations provide a level for measuring a level of a target surface. The level has a base structure having a bottom surface, a top surface, a rear surface, and a front surface, and a bubble level disposed on the top surface of the base structure. The bottom surface is disposed at (1) a desired slope angle of the target surface along a first axis, and (2) a predetermined pitch angle along a second axis of the base structure, the second axis perpendicular to the first axis. The bubble level is disposed on the top surface along the first axis to indicate a slope level of the target surface relative to the predetermined slope angle and along the second axis to indicate a pitch level of the target surface relative to the predetermined pitch angle. The base structure has a ledge extending in an engagement direction along a third axis.

The present disclosure discloses a device (100) for determining orientation of an object. The device includes a hollow spherical member (101), which is filled with a fluid medium (109). A plurality of sensors (102) is positioned on a circumference of the hollow spherical member. Further, the device comprises a light source (104) fixed within the hollow spherical member, and a capsule (103) is disposed within the hollow spherical member. The capsule is configured to displace within the hollow spherical member and occupy uppermost point of the hollow spherical member. The capsule covers the one or more sensors at the corresponding uppermost point and, thus blocks impingement of light on to corresponding one or more sensors. The blocked one or more sensors activate or deactivate, and generate a feedback or input signal, which is received by a computing unit (107), to determine orientation of the object.
