    en.wikipedia.org/wiki/Level_sensor

    Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface. Substances that flow become essentially horizontal in their containers (or other physical boundaries) because of gravity whereas most bulk solids pile at an angle of repose to a ...

    When sensors were placed on desktops in an office building, an penalty of 24% on energy saving occurred. [7] In both the open- and closed-loop configurations, the signal from the photosensor must be carefully calibrated to accurately indicate the effect of exterior daylight variations on the light level on 'important function' areas in the space.

    en.wikipedia.org/wiki/Mechanical_systems_drawing

    Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, air conditioning and transportation around the building (Elevators or Lifts and Escalator). [1] It is a powerful tool that helps analyze complex systems. These drawings are often a set of detailed drawings used for construction projects ...
