1. A method for monitoring content within a container, the method comprising:
transmitting, from a source positioned external to the container, at least one signal into the container through an external surface thereof, wherein a frequency of the at least one signal varies over time;
determining a time of reception of a response to the at least one transmitted signal, wherein the response is received within a time window defined to exclude signals arriving outside a predetermined range following transmission of the at least one signal;
determining, based on the time of reception of the response received within the time window and the frequency variation of the at least one transmitted signal, a distance to at least one content within the container generating the response; and
providing an indication of a level of fill of at least one of the at least one content within the container.
