Zusammenfassung:	Liquid level sensing apparatus are disclosed. An example liquid level sensing apparatus includes a cannula defining a body having a tip and an access channel. The tip to pierce a container, where the cannula is to be at least partially positioned in the container when the tip pierces the container. A probe is to be positioned in the access channel. A signal source is to electrically energize the probe and the cannula to cause the probe to emit a first signal and cause the cannula to emit a second signal.
