Description:
Illustration for the mass flow meter article, for the purpose of illustrating the mass flow meter operating principle; actual mass flow meters are not designed this way.
This is the second animation of a group of four.
The previous animation is Image:Coriolis_meter_rotating_no-flow_512x512.gif
The next animation is Image:Coriolis_meter_vibrating_no-flow_512x512.gif Fluid is being pumped through the mass flow meter. When there is mass flow, the tube twists slightly. The arm through which fluid flows away from the axis of rotation must exert a force on the fluid, to increase its angular momentum, so that are bends backwards. The arm though which fluid is pushed back to the axis of rotation must exert a force on the fluid, to decrease the fluid's angular momentum again, hence that arm will bend forward. Summerizing: the inlet arm is lagging behind, the outlet arm is pulling ahead. A flow meter that uses the Coriolis effect for its operating principle is also called a Coriolis flow meter.
