摘要： A micrometer system and water holding cup and related for use in connection with a hydrostatic level-measuring system for measuring with precision, a level normal to gravitation of physical surfaces, the micrometer system comprising: a micrometer; an elongated micrometer probe tip at a lower extremity of the micrometer; a micrometer dial for extending and retracting the probe tip in response to a dialing thereof; a micrometer alignment section fixed to the micrometer, and a substantially rigid support structure for supporting the a micrometer alignment section at a fixed height above the physical surfaces when a footing of the support structure is rested upon the physical surfaces. The cup comprises mirroring on a bottom surface thereof; at least one reference feature on the mirroring surface for providing to a user, a visual reference for at least one micrometer grade marker reflected by the mirroring surface, for dialing a micrometer.

摘要： A water-holding cup for use in connection with a hydrostatic system for measuring with precision, a level normal to gravitation of a surface, said cup comprising: a cup height h thereof from a bottom to a top of said cup when said cup is resting upon the surface, which cup height h is known a priori within acceptable measurement errors; mirroring on a bottom surface of said cup; and at least two water outlets for fluidically interconnecting said cup with other like-cups, said outlets oriented at a fitting angle of at least five (5) degrees downward.
