A top reading liquid sight level indicator that mounts above a liquid contained in a liquid vessel, comprising:
- a measuring element mounted to a surface of the liquid vessel above the contained liquid with a measuring surface facing the vessel surface that penetrates an upper surface of the contained liquid at a cant from normal to the liquid surface;
- wherein the points along the measuring surface that penetrate the liquid surface are visible from above the liquid vessel and represent the level of the liquid in the liquid vessel.
A top reading liquid sight level indicator that mounts above a liquid contained in a liquid vessel, comprising:
- a mounting frame that couples to a surface of the liquid vessel above the contained liquid;
- a measuring element coupled to the mounting frame with a measuring surface facing the vessel surface comprising at least one measuring surface portion comprising a staircase-like surface with a plurality of steps that penetrates an upper surface of the contained liquid and approximates a surface that cants from normal to the liquid surface;
- and
- a liquid-tight sight glass that mounts within the mounting frame to provide a view of the measuring surface from above the liquid vessel;
- wherein the points along the measuring surface that penetrate the liquid surface are visible from above the sight glass and represent the level of the liquid in the liquid vessel.
