Liquid dispensing and recirculating system with sensor

A probe for dispensing liquid from and returning liquid to a container comprising:

• a flow passage extending through the probe from a first end of the probe to a second end of the probe;
• a fluid return port;
• and
• a fluid return channel in fluid communication with the fluid return port via a bore, the fluid return channel extending longitudinally along an exterior of the probe substantially parallel to the flow passage from the bore to about the second end of the probe.

A method of dispensing and recirculating liquids comprising:

• providing a container having a mouth which communicates with an interior of the container;
• attaching a cap over the mouth;
• coupling a connector to the cap, wherein the connector includes a probe defining a fluid passage terminating within the interior of the container at a tip of the probe;
• defining a fluid return channel on the probe;
• dispensing fluid from the container through the fluid passage;
• and
• refilling fluid into the container through the fluid return channel such that air in the fluid is released above the fluid in the container to prevent injection of air into the fluid in the container.
