Quality-checking method for recognizing quality in a liquid medium in a container uses a distance-measuring device to calculate geometric dimension and density

摘要

Using a distance-measuring device (6) applies known geometry and mass to determine the depth of immersion (he) for a float (2) fitted in a container and partly immersed in a medium. By utilizing one of the depths of immersion, a geometric dimension is deduced from known geometries and the density of a liquid medium is calculated from the mass.
