Precision Hydrostatic Level and Flatness Measuring Devices, Systems and Methods

A method for using a micrometer system in connection with a hydrostatic level-measuring system for measuring with precision, a level normal to gravitation of physical surfaces, comprising:

• providing a micrometer system comprising a micrometer, an elongated micrometer probe tip at a lower extremity of said micrometer, a micrometer alignment section fixed to said micrometer, and a substantially rigid support structure for supporting said micrometer alignment section at a fixed height above the physical surfaces;
• resting footings of said support structure upon a first measured physical surface wherein that said micrometer alignment section forms a bridge over a first water-holding cup;
• extending and retracting a micrometer extension head of said micrometer system by dialing a dial of said micrometer until said probe tip contacts a top surface of water within said first cup, thereby forming a first meniscus visible to a user when said contact occurs;
• recording a first reading from said micrometer based the first meniscus formation;
• moving the micrometer system and resting said footings upon a second measured physical surface such that said micrometer alignment section forms a bridge over a second water-holding cup fluidically-interconnected with said first cup;
• extending and retracting said micrometer extension head by dialing a dial of said micrometer until said probe tip contacts a top surface of water within said second cup, thereby forming a second meniscus visible to a user when said contact occurs;
• recording a second reading from said micrometer based on the second meniscus formation;
• and
• comparing said first and second readings to deduce a level difference between the first and second physical surfaces.

A method of using a water-holding cup in connection with a hydrostatic system for measuring with precision, a level normal to gravitation of a surface, comprising:

• providing mirroring on a bottom surface of said cup;
• providing at least one reference feature on said mirroring surface;
• placing a micrometer system above said cup, said micrometer system comprising a micrometer, a micrometer extension head, and a calibration protractor comprising at least one grade marker situated on a bottom of said extension head;
• said mirroring surface reflecting at least one micrometer grade marker by virtue of said placement;
• and
• the user precisely dialing said micrometer, by using as a visual reference, a reflection of said at least one grade marker off of said mirroring surface against said at least one reference feature on said mirroring surface.
