DEFINITION

Classification: 374/135

By fluid flow within or to sensor (e.g., convection, heat transfer, differential pressure):

(under subclass 120) Subject matter including determination of some parameter of a flowing fluid in thermal relationship to an object at a location spaced away from the object.

(1) Note. Convection current measurement is included herein.

(2) Note. The parameters of the flowing fluid include flow rate, pressure, and temperature.
