Abstract
An electromagnetic flow meter is disclosed which can be used to measure flow in low conductivity fluids, for example alcohol, turpentine, oil or other organic solvents. In one embodiment, the electromagnetic flow meter includes an elongate flow conduit having a direction of elongation corresponding to a direction of fluid flow, magnetic field generating means for generating a magnetic field across the flow conduit and potential sensing electrodes for sensing a potential generated by the magnetic field in a fluid flowing through the conduit. Both the field generating means and the potential sensing electrodes of the flow meter are elongate in the direction of flow.
