摘要

Method for determining the liquid level in a container (10) comprises using an evaluation unit to determine the filling level from the signal strength from a received signal. An independent claim is also included for a device for determining the filling level of a reservoir. Preferred Features: The evaluation unit determines the signal strength of the received signal using a load measurement on an emitter (15). A signal of a different frequency is back-scattered. The value of the signal strength is transferred as a digital code. An RF signal is used.
