  • Oil separator structure for an oil collector blower
    Patent number: 6214071
    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 magnetic field generated by the magnet and outputs an electrical signal which is representative of a height of the fluid level.
