DEFINITION

Classification: 210/746

Electrical property sensing:

(under subclass 739) Process in which the conductivity, impedance, or capacitance of the liquid or constituent is determined and is the basis for response by actuating means.

(1) Note. The use of an electrical property to determine some other property (e.g., pH, temperature) is classifiable

in the appropriate subclass above providing for those concepts.
