ABSTRACT:
An apparatus for measuring the vertical displacement of a plurality of horizontally spaced locations on a variety of surfaces is disclosed. A fluid reservoir having a plurality of outlets is freely suspended on a support means, such as a tripod. A plurality of measuring means, at horizontally spaced locations, are connected to the plurality of fluid reservoir outlets. Each measuring means is then separately calibrated to a desired vertical height at its particular horizontal location to establish a reference point. Once the measuring means is calibrated, a single operator can determine to what degree a plurality of horizontally spaced locations are either higher or lower than the reference point. Additionally, a leveling apparatus is disclosed which also allows a single operator to determine the vertical displacements of a plurality of horizontally spaced locations.
