Method for defining a filling level measurement range

Abstract

A method for defining a fill level measurement range for travel time-based measurement of fill levels in containers includes placing a travel time-based, fill level measuring device at the upper end region of a container and measuring the distance to the container floor in the case of empty container such that the fill level measurement range is defined both relatively and absolutely, in that the limits of the measuring range are determined based on the measured distance value. Defined as lower limit is the measured distance value. In the case of a relative measuring range, the upper measuring range limit is defined by multiplying the measured distance value by an earlier determined factor of maximum 1. Advantageous in the method is that the fill level measuring device can be used without calibration and without knowledge of the geometry in the interior of the container.
