It is desirable to be able to indicate the quantity of liquid left in the fuel tank of a vehicle. This is conventionally achieved with the aid of a float movable along a resistance wire. The invention offers an improved design of a liquid gauge consisting of two parallel rods (16 and 17),having resistance wires (18,19 respectively) wound around them and being surrounded by a float (6,7,15) with a contact (1-5) connecting the two resistance wires (18 and 19) to each other and arranged between the two wires (18 and 19).

In a liquid level indicator system having a resistance component, a contact component adjustably engaging said resistance component, and a float mounted for movement relative to said resistance component for adjustably varying the engagement of said contact component with said resistance component upon movement of said float; the improvement comprising the resistance component including two vertically elongate bodies, said bodies being in parallel laterally spaced relation to each other, each of said bodies terminating in opposed ends generally coextensive with the ends of the other body, and an outer electrically conductive layer about each body between the opposed ends thereof, the float surrounding said elongate bodies for vertical movement therealong, said float comprising opposed parallel spaced end discs with a guide means therebetween, said end discs having aligned apertures therethrough slidably receiving the eongate bodies through said guide means and precluding relative rotation between the float and the elongate bodies, and the contact component comprising two conductive contacts in electrical contact with each other, each contact engaging against a separate one of said electrically conductive layers on the bodies, and means fixing said contacts to said float for vertical movement therewith along said vertically elongate bodies.
