How does a Coriolis flow meter work?

A Coriolis flow meter measures mass flow by detecting the Coriolis effect on vibrating tubes. When fluid flows through tubes vibrating at their resonant frequency, the Coriolis force causes a phase shift between inlet and outlet tube movements proportional to mass flow rate. Coriolis meters directly measure mass flow without requiring density compensation, provide high accuracy (0.1%), and can simultaneously measure density and temperature.
