Medium filling level determining and monitoring method for e.g. freely radiating microwave measuring device, involves adjusting shielding curve, evaluation curve and/or echo parameter based on change of position and/or amplitude of signals

摘要

The method involves transmitting a transmission signal (S) in a direction of a medium (7) and receiving a reflection signal (R). A continuous echo result of position change and/or amplitude change of individual echo signals and/or useful echo signals is implemented in an echo function by a dynamic echo search algorithm. Shielding curve, evaluation curve and/or an echo parameter of a static echo search algorithm is adjusted based on the position change and/or amplitude change of the individual and/or useful echo signals of the echo result by the dynamic echo search algorithm.
