1. A liquid-level gauge comprising,
a body of transparent material having a head part connected to an elongated part with an end region vertically disposable through a matching socket with a collar to be engaged with a liquid-level in the enclosure tank, the body of transparent material allowing a vertical line of sight from outside via the head part to the end region inside the matching socket, the end region including two facets formed from two opposing peripheral sides of the elongated part toward a common linear tip portion with an angle of approximately 45 degrees relative to the vertical line; a first planar opaque member partially inserted in a slot cut from the linear tip portion along the vertical line into the elongated part, the first planar opaque member bearing a first legend on each of two opposite sides; and a second planar opaque member perpendicularly coupled with the first planar member and attached at the linear tip portion to form two half planes bearing a second legend facing the two facets respectively; wherein the first legend is visible from the head region when the two facets are fully above the liquid-level in the enclosure tank; wherein the second legend is visible from the head region when the two facets are fully submerged below the liquid-level at a normal range in the enclosure tank; wherein a dimmed view with neither the first legend nor the second legend being clearly visible is still an indicator that the liquid-level is below normal range. |
