Description

A simple mechanical unit with a glass face and analog scale inside the unit that reads in pounds per square inch or the percentage of the remaining fuel. This design is a propane tank accessory and is placed between the tank and the regulator that indicates the current pressure within the tank. Consequently this apparatus enables the user to determine the level of fuel in the propane tank, thereby knowing beforehand the level of fuel in the propane tank.

FIG. 1 is a front perspective view showing my design;

FIG. 2 is a back perspective view;

FIG. 3 is a right side perspective view;

FIG. 4 is a left side perspective view;

FIG. 5 is a bottom perspective view; and,

FIG. 6 is a top perspective view.

Portions of the tube member has been eliminated for ease of illustration.
