Abstract
This invention relates to an attitude meter which measures the orientation of a plane surface with respect to the magnetic North direction and a horizontal plane. The meter includes a hollow transparent sphere containing liquid for supporting a compass and a vertical indicator, combined with a rotatable arcuate scale for facilitating visual reading of the compass and relative position of the vertical indicator. More particularly, the arcuate scale includes vertical orientation indicia and is mounted for rotational displacement to a position immediately adjacent the vertical indicator. By this arrangement the vertical angle of the surface being measured may be read directly from the arcuate scale and the direction of inclination relative to the magnetic North may be determined from the point of intersection of the arcuate scale and the liquid supported compass.
