Measuring Device and Method for Measuring the Level of a Liquid in a Container

摘要

A measuring device for measuring a level of a liquid in a container is disclosed. The measuring device comprises a sensor line and a float. The sensor line has a plurality of magnetic-field sensors, at least one of the plurality of magnetic-field sensors uses a magnetoresistive effect or is a Hall effect sensor or a magnetoresistor or an extraordinary magnetoresistive sensor. The float is movable along and relative to the sensor line between a first measuring location and a second measuring location. The float has a magnet generating a magnetic field extending substantially parallel to the sensor line at both the first measuring location and the second measuring location.
