Claim of US Patent No. 9,631,961

1. A magnetic inductive flow meter, comprising:
a flow tube having an inlet, an outlet and a measuring channel positioned between the inlet and the outlet;
a first electrode and a second electrode positioned on opposite sides of the measuring channel;
a pair of magnetic pole pieces positioned on opposite sides of the measuring channel and orthogonal to the first and second
electrodes, wherein a portion of each of the magnetic pole pieces is positioned to overlap each of the first and second electrodes;
and

an electromagnet coupled to the pair of magnetic pole pieces and configured to generate an alternating magnetic field across
the measuring channel.
