Abstract
A single plate capacitive bubble detection sensor. The detector may employ a single active plate. A parasitic capacitance of the active plate relative to the environment may be monitored without reference to any particular ground source. In this regard, highly sensitive measurements may be made of a tube disposed adjacent to the active plate to detect, for example, the presence of air, liquid, or a change between liquid and air in the tube.
