    Abstract: A mechanism for performing capacitive level sensing of fluid within a fluid container supported on a movable carrier comprises a conductive probe, a probe position sensor, and a movable grounding element. The probe is configured for capacitive level sensing by detecting a signal or change of signal based on capacitance when the probe, or a conductive tip removably attached to the probe, contacts the surface of the fluid within the container. The probe position sensor is for monitoring a vertical position of the probe and recording the position at which the signal or change of signal is detected. The movable grounding element is configured for selective movement relative to a container positioned by the movable carrier at a level-sensing location with respect to the probe until the grounding element is in close proximity to or in contact with a portion of the container.

    Abstract: There is disclosed herein a level detection system includes a housing (120) having a plurality of wall portions defining a receiving space for a container (200). The system further includes a capacitor having a first plate (142a) and a second plate (142b), the wall portions including a first wall portion having the first plate (142a) and a second wall portion having the second plate (142b). When the container is in the receiving space, a capacitance of the capacitor depends on a level of substance in the container (200). The system also includes a processor configured to determine the level of the substance in the container (200) based on the capacitance of the capacitor.
