ABSTRACT:
The invention relates to a vessel apparatus for holding and transferring liquids, in which the level of liquid may be controlled and monitored automatically. A depth sensing device, included in the apparatus, detects the presence or absence of liquid at predetermined levels. The device detects the difference in transmission of a low frequency electromagnetic signal between aerial probes based on the state of immersion (wet or dry) of the transmitting and receiving probes.
