Oil Sight Glass

Abstract

The present disclosure relates, in one embodiment, to an oil sight apparatus. The oil sight may include a sight body with a chamber defined in the sight body. The chamber may include a top, a bottom, and a sidewall spanning from the top to the bottom. A separator may be located in the chamber. The separator may be configured to sink in oil and to float in water such that the separator may rest at an oil-water separation line in the chamber.

What is claimed is: 
     
         1 . A sight glass comprising:
 a sight body;   a chamber defined in the sight body, the chamber including a top, a bottom, and a sidewall spanning from the top to the bottom; and   a separator located in the chamber, the separator configured to float in a first fluid and sink in a second fluid such that the separator rests at an interface between the first fluid and the second fluid in the chamber.   
     
     
         2 . The sight glass of  claim 1 , wherein:
 the chamber bottom includes an opaque bottom section such that at least some ambient light reflects off of the opaque bottom section and into the chamber.   
     
     
         3 . The sight glass of  claim 2 , wherein:
 a majority of the chamber bottom includes the opaque bottom section.   
     
     
         4 . The sight glass of  claim 1 , further comprising:
 an illumination source located nearer the chamber bottom than the chamber top.   
     
     
         5 . The sight glass of  claim 4 , wherein:
 the illumination source is located below the chamber bottom opposite the chamber top.   
     
     
         6 . The sight glass of  claim 4 , wherein:
 the illumination source is disposed at least partially within the chamber bottom.   
     
     
         7 . The sight glass of  claim 4 , wherein:
 the illumination source is electrically connected to a remote light switch.   
     
     
         8 . The sight glass of  claim 1 , wherein:
 the chamber top includes a domed top to prevent at least some exterior contaminants from resting on the chamber top.   
     
     
         9 . The sight glass of  claim 8 , wherein:
 the domed top includes a curvature that is equivalent to a surface of a sphere with a radius from 10 inches to 30 inches.   
     
     
         10 . The sight glass of  claim 9 , wherein:
 the curvature is equivalent to a surface of a sphere with a radius of 20 inches.   
     
     
         11 . The sight glass of  claim 8 , wherein:
 the chamber top includes a transparent top section to allow a user to look into the sight glass from above.   
     
     
         12 . The sight glass of  claim 11 , wherein:
 the chamber top is shaped such that the domed top acts as a magnifying glass.   
     
     
         13 . The sight glass of  claim 1 , wherein:
 the chamber bottom includes an angled chamber bottom to drain at least one of the first fluid and the second fluid.   
     
     
         14 . The sight glass of  claim 13 , wherein:
 the angled chamber bottom includes a bottom elevation difference of 0.05 inches.   
     
     
         15 . The sight glass of  claim 1 , wherein:
 the separator includes an overall density greater than 800 kilograms per cubic meter and less than 1000 kilograms per cubic meter.   
     
     
         16 . The sight glass of  claim 1 , wherein:
 the separator includes a plurality of separators.   
     
     
         17 . The sight glass of  claim 16 , wherein:
 the plurality of separators are of a number such that the plurality of separators occupies a majority of the interface between the first fluid and the second fluid in the chamber.   
     
     
         18 . The sight glass of  claim 16 , wherein:
 the plurality of separators includes a plurality of spheres.   
     
     
         19 . The sight glass of  claim 1 , wherein:
 the chamber top includes a first opening defined therein;   the chamber bottom includes a second opening defined therein, the second opening being larger than the first opening; and   the separator is sized such that the separator may pass through the second opening but may not pass through the first opening.   
     
     
         20 . The sight glass of  claim 1 , wherein:
 the separator includes a surface configured to prevent at least some bubbles from forming on the surface.
