Abstract
An electromagnetic flowmeter comprising a body having a central channel having a measuring region, an inlet region and an outlet region. Relative to liquid flow through the central channel, the inlet region is upstream of the measuring region, and the outlet region is downstream of the measuring region. The inlet region and outlet region have diameters substantially greater than the diameter of the measuring region. A transition region extends between the inlet region and the measuring region, and a transition region extends between the measuring region and the outlet region. First and second cavities are respectively positioned in the inlet region and the outlet region, and third and fourth diametrically opposed cavities extend from the measuring region of the central channel. First and second grounding electrodes are respectively positioned in the first and second cavities, and third and fourth measuring electrodes are respectively positioned in the third and fourth cavities.
