Abstract

A fluid level measuring gauge for accurately measuring and reading a fluid level in a fluid level access chamber having one or more bends and interior chamfered shoulder zones, the fluid level measuring gauge including an elongate blade having an upper and lower portion where the upper and lower portions of the fluid level measuring gauge are in a constant twist formation for creating a nonwiping motion during insertion of the fluid level measuring gauge into and out of a fluid gauge access chamber, a flat shaped measuring region, including an upper port and a lower port in an up and down direction on the measuring region, a handle attached to the blade for controlled insertion and removal of the fluid level measuring gauge, and a spherical chamfer advancing guide affixed to the leading end of the elongate blade, opposite the handle.

Claims (7)

1. A fluid level measuring gauge for accurately measuring and reading a fluid level in a fluid gauge access chamber having one or more bends or interior chamfered shoulder zones, said fluid level measuring gauge comprising: an elongate blade having an upper zone and lower zone wherein said upper and lower zones of said measuring gauge are in a constant spiral formation for creating a nonwiping motion during insertion of said fluid level measuring gauge into and out of a fluid gauge access chamber; a flat shaped measuring region, including a plurality of ports aligned in an up and down direction on said measuring region; a handle attached to said blade for controlled insertion and removal of said fluid level measuring gauge; and a spherical chamfer advancing guide affixed to the leading end of said elongate blade opposite said handle.

2. The gauge of claim 1 , wherein said measuring region is located between said upper and lower zones.

3. The gauge of claim 1 , wherein said lower zone includes at least one complete 360 degree twist.

4. The gauge of claim 3 , wherein said lower zone is located immediately adjacent to said spherical chamfer advancing guide.

5. The gauge of claim 1 , wherein the constant spirals are at approximate 180 degrees of each other.

6. The gauge of claim 1 , wherein the spherical chamfer advancing guide is welded to end of said gauge.

7. The gauge of claim 1 , wherein two ports are oriented adjacent fluid level measuring indicia.
