Abstract
An electromagnetic flow meter for measuring flow rate of a fluid passing therethrough includes a conduit defining a fluid inlet, a fluid outlet and a measuring section positioned between the inlet and the outlet. The flow meter also includes a single coil for generating a magnetic field across the measuring section and electrodes for detecting induced electrical potential due to the fluid passage. The coil may be arranged to surround a section of the measuring section over a segment angle of between 140 and 180 degrees. The electrodes may be positioned so that they are offset from being opposite each other on the centerline of the measuring section, by an offset angle of between 5 degrees and 45 degrees.
