| Zusammenfassung: | A liquid level sensing system, including: an input acoustic waveguide, and an output acoustic waveguide, positioned extending into liquid to be sensed; the input waveguide being arranged to receive acoustic energy; an acoustic sensor attached to the output waveguide for sensing acoustic energy at the output waveguide that has been transferred from the input waveguide to the output waveguide by being acoustically coupled by the liquid; and a processor arranged to process timing characteristics of the sensed acoustic energy to determine a measure of the liquid level. |
