binding as the floats 12 move up in the tube 4 the floats 12 move up in the gauge 100 as the liquid rises in the tank 17 such that when the floats 12 rise to the full marker 10 within the tank 17 the rising pointer 5 will simultaneously reach the full indicator 2 to indicate that the fluid level in tank 17 will have reached the full marker 10 positioned inside the tank 17 riser arm or rod assembly 11 is preferably made of a single rigid wire such as copper or some other similar material at each end the wire is formed into separate riser arm guides 6 as seen more clearly in fig7 riser arm guides 6 generally take the shape of two substantially perpendicular triangles which when viewed from the top or bottom generally forms an u201c x u201d shape at each end of the riser arm 11 this design minimizes the surface area of wire that touches the inner walls of tube 4 this substantially eliminates any sticking or binding as the riser arm 11 moves upward within the gauge 100 the riser arm assembly 11 optionally has a bright colored rising pointer 6 positioned at the top end to clearly indicate when it reaches full indicator 2 the rising pointer 5 is made of.
