OSTI ID:6975379
This patent describes an automatic reading gauge for fluid within a tank. It comprises: an O-shaped hollow body having at least one weep hole at a lower end to allow the fluid to enter the body, at least one air check valve at an upper end to allow air to exit the body and a top sight area; an elongated flexible measuring member having a scale thereon, the measuring member disposed with the body so that the scale can be viewed through the top sight area; a float affixed to one end of the measuring member within the body; a counterweight affixed to other end of the measuring member within the body to keep the measuring member taut so that when the body is placed through a filler hole in the tank to extend to bottom of the tank the fluid entering the body will cause the float to rise giving a reading of the scale of the measuring member at the sight area thus indicating the amount of fluid within the tank; wherein the body is telescopic.
