DEFINITION

Classification: 73/861.351

Mass flow by imparting angular or transverse momentum to the fluid:

(under subclass 861) Subject matter wherein a fluid is accelerated in a direction other than the normal direction of flow and a response related to the acceleration is determined to provide a direct measurement of mass flow.

SEE OR SEARCH THIS CLASS, SUBCLASS:

861.01, through 861.03, for a mass flow measurement in which the volume of flow is combined with another measurement to provide a measurement of mass flow.

861.32, for a device responsive to the angular velocity imparted to a fluid
