There is provided a liquid level sensor apparatus that has particular and beneficial application in a fuel tank, such as a saddle-tank used in automotive vehicles comprising first and second fuel compartments. The liquid level sensor apparatus is for determining a level or quantity of fuel therein. The liquid level sensor apparatus comprises means for issuing an electrical signal indicative of a level or quantity of liquid, such as a sender unit comprising a motion-responsive potentiometer. Additionally there is provided a first float assembly that is moveable in response to a first liquid level. The first float assembly is coupled directly to said means such that in response to movement of the first float assembly an electrical characteristic of said means is affected and an electrical signal issued by said means is indicative of said first liquid level. Furthermore, there is provided a second float assembly that is moveable in response to a second liquid level. The second float assembly is indirectly coupled to said means and in such a way that in response to movement of the second float assembly an electrical characteristic of said means is affected and an electrical signal issued by said means is indicative of said second liquid level.

A liquid level detection device is provided with a fixed body and a rotating body, and includes a float and an arm. The arm has an insertion portion to be inserted in the rotating body and an extending portion extending straight and bent relative to the insertion portion. The rotating body has an insertion hole in which the insertion portion is inserted in an insertion direction, a holding portion having a receiving opening receiving the extending portion in an intersecting direction intersecting with the insertion direction and holding the extending portion received by the receiving opening, and a stopper releasing the receiving opening by moving in the insertion direction due to elastic deformation from a blocking state in which a blocking portion blocks the receiving opening. The stopper has a sliding surface portion facing an opposite direction to the insertion direction, on which the extending portion is allowed to slide. A thickness of the blocking portion in the insertion direction at a tip end of the sliding surface portion is greater than a diameter of the extending portion.

A filling level indicator includes a retainer, a bow rotatably supported on the retainer and having a lever arm fastened thereto, a float fastened to the lever arm, and a filling level sensor arranged in the retainer. The filling level sensor has a substrate, a resistance network arranged thereon, a contact spring structure, and a cover, connected to the substrate, that covers the resistance network and the contact spring structure. A magnet is connected to the bow or the lever arm and acts on the contact spring structure such that an electrical signal corresponding to the filling level is generated according to the pivoting range. The mount has a wall thickness that can be penetrated by the magnetic field of the magnet, and so metal particles are held on the outside of the mount by the magnetic field of the magnet.

An angle detection device for a fuel fill level detection device, including: a support, a potting composition, which is arranged on the support in coherently bonded manner; a sensor for the contactless detection of an orientation of a magnetic field of a magnet, which is at least partly arranged in the potting composition, in particular on the support, and at least one conductor track which is arranged flat on the support, in particular in coherently bonded manner.
