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.

Claims (44)

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, wherein the top includes a first opening defined therein, the bottom includes a second opening defined therein, and the first opening and second opening are offset in relation to one another;

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; and

wherein the sight glass is operable in a vertical and a horizontal orientation.

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 second opening is 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.
