17. A method for dispensing liquid into a container, the method comprising:
flowing liquid into the container;
propagating, by causing a lever arm of a vibration generator to contact the container, one or more vibrations through the container at predetermined intervals;
measuring, via a measurement device, a characteristic of the one or more vibrations propagating through the container at the predetermined intervals;
receiving, by a controller, one or more signals indicative of the characteristic of the one or more vibrations propagating through the container at the predetermined intervals;
determining, by the controller, a liquid level of liquid within the container based at least in part on the one or more signals indicative of the characteristic of the one or more vibrations propagating through the container at the predetermined intervals.
