Abstract
A contact free flow meter for determining the velocities and/or flow directions of electrically-conductive fluids is disclosed. At least one primary magnetic field is arrayed generally perpendicular to the flow path, the field having strength gradients extending along the flow path. At least two magnetic field sensors are spaced apart in the direction of the flow path the sensor being responsive to the magnetic field. The device is capable of functioning notwithstanding electrically-conductive material such as pipe walls interposed between the fluid and the meter.
