ABSTRACT:
This invention relates to a positive displacement flow meter or pump comprising a plurality of spherical balls orbitably entrained in a toroidal cavity. The first segment of the toroidal cavity tangentially connecting a fluid inlet to a fluid outlet comprises the flow passage for the fluid being measured or pumped and the second segment provides the return pass for the spherical balls. A rotating magnetic field about the line of axisymmetry of the toroidal cavity generates the orbiting movement of the spherical balls for measuring the flow rate or for pumping.
