Abstract
Liquid level sensing apparatus and related methods are disclosed. An example method includes moving a cannula to pierce a seal of a container to provide access to a liquid in a cavity of the container; moving a probe through a passageway of the cannula and into the cavity of the container; and when the probe is at least partially positioned in the cannula: providing a first signal to the probe to cause the probe to emit a first electrical field; and providing a second signal to the cannula to cause the cannula to emit a second electrical field.
