摘要： The invention relates to an automated liquid level sensing system for detecting the presence of liquid in a container, said liquid level sensing system comprising: a vertically oriented, electrically conductive probe positioned above said container; means for vertically moving said probe into and out of said container; a signal source electrically connected to said probe, said signal source energizing said probe with an electrical signal and causing said probe to transmit said electrical signal; a receiving antenna positioned below said container for receiving said transmitted electrical signal; means for analyzing said received electrical signal for indications that said probe has contacted liquid in said container; means for transferring said received electrical signal from said receiving antenna to said analyzing means; and means for indicating that liquid has been detected. Further, the invention also provides for a method for automatically detecting the presence of liquid in a container, said method comprising the steps of: vertically positioning an electrically conductive probe above said container; vertically moving said probe into and out of said container; electrically connecting a signal source to said probe, said signal source energizing said probe with an electrical signal and causing said probe to transmit said electrical signal; positioning a receiving antenna below said container for receiving said transmitted electrical signal; analyzing said received electrical signal for indications that said probe has contacted liquid in said container; transferring said received electrical signal from said receiving antenna to said analyzing means; and indicating that liquid has been detected.
