DEFINITION

Classification: 73/170.08

Electric sensor:

(under subclass 170.07) Subject matter including means whose electron flow or electron storage characteristic changes in response to the determination being made.

SEE OR SEARCH THIS CLASS, SUBCLASS:

170.09, for fluid flow direction determination means not combined with velocity measuring but having an electric sensor which is responsive to fluid flow direction.

866.5, for a probe or probe mounting, per se.
