Abstract
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.

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.
A method of using a water-holding cup for measuring with precision, a level normal to gravitation of a surface, said method comprising:
- providing said water-holding cup with 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;
- providing mirroring on a bottom surface of said cup;
- and
- providing at least two water outlets of said cup for fluidically interconnecting said cup with other like-cups, said outlets oriented at a fitting angle of at least five (5) degrees downward.
