ABSTRACT:
The present disclosure provides several systems. In general, it provides E-field sensor systems that utilize at least one electrode100adapted for creating an E-field in an area210within a detection volume where fluid presence400or presence of a solid body300is to be detected. The electrical field sensor is configured to generate a detected signal responsive to a change in capacitance of the electric field, and is communicatively coupled to the electrode100. In addition, a processor275is configured to determine a quantitative measure of a fluid or solid body within the detection volume in accordance with a capacitive relationship with the detection volume. Described are examples of the system for fluid presence detection, fluid level measurement and measurement of proximity to a solid object.
