Patent abstract
In a method for the capacitive fill level measurement of a fill substance in a container, electrical current is determined at two alternating voltage signals U1, U2 of differing frequencies f1, f2. On the basis of the two values for current, the capacitive reactance and therewith the fill height h of the fill substance can be easily determined. Influences of ohmic resistance on the measurement results are eliminated in this method.
