DEFINITION

Classification: 73/861.12

With detecting electrodes:

(under subclass 861.11) Subject matter wherein electrodes are placed in contact with the fluid or are capacitively coupled therewith to detect a potential gradient produced in the fluid along a path through the fluid extending transverse to both the magnetic field and a component of the flow direction.
