Abstract
A fluid level measuring device for measuring a fluid filling level in a container contains a float disposed in the container and a magnet disposed in the container. The magnet is coupled to the float in terms of movement and, in the event of a change in the fluid filling level, executes a movement that corresponds to a change in fluid level. A magnetic field sensor is disposed in a zone of influence of a magnetic field generated by the magnet and outputs an electrical signal which is representative of a height of the fluid level.
Claims14
In a container containing a fluid, a fluid level measuring device for measuring a fluid filling level in the container, the fluid level measuring device comprising:
- a float disposed in the container and having a given relative density less than a relative density of the fluid;
- a magnet generating a magnetic field disposed in the container and coupled to said float in terms of movement and, in an event of a change in the fluid filling level said magnet executes a movement corresponding to the change in the fluid filling;
- and
- a giant magneto resistor sensor disposed outside of the container in a zone of influence of the magnetic field generated by said magnet and outputs an electrical signal representative of a height of the fluid filling level of the container, said giant magneto resistor sensor serving to obtain contactless information concerning the fluid filling level.
