ABSTRACT:
Apparatus for measuring mass flow of a fluid in a conduit by which the fluid passes through a moveable chamber which establishes a constant velocity profile of the flowing fluid at the outlet opening of the chamber. Measurement of momentum force at the control surface defined by the outlet opening of the chamber permits accurate mass flow measurements by application of the momentum equation.
