Magnetic level gauge indicator with ultra-wide viewing angle

摘要

A level gauge for determining the level of a liquid in a vessel includes lenticular lens assembly allowing a plurality of level indicator flags enclosed therein to be viewed from a wide angle. The indicator flags have an elongated body manufactured from a sheet of material, and form a central pocket for retaining a magnet, and pins on either end for mounting within a frame. A mounting frame positions the lens assembly whereby an open channel is formed between the lens assembly and a back plate. The mounting frame is mounted to the vessel using spacers forming an open gap between the mounting frame and vessel. The open channel and gap minimize the transfer of heat from the vessel to the level gauge. The passage of a float with a magnet on the liquid in the vessel rotates the flags.

1. A level gauge, comprising:
a lens assembly, comprising:
an elongated tubular body extending from a top end to a bottom end, having an interior surface and exterior surface, the lens assembly comprising: a rear wall; and a front face, comprising:
a center pane aligned on a centerline extending perpendicular from the center of the rear wall;a left lateral extending rearward from the center pane toward a left wall;a right lateral extending rearward from the center pane toward a right wall; andwherein each of the left lateral and right lateral form a lenticular lens.
