Grounding electrode electromagnetic flowmeter can reduce the loss of measurement signal,and conductivity lower medium be measured if area grounding was increased. However, is increased, signal will reduced. The weight function theory flow meter shows that reason distribution functions changed by electrode, lead to induced electromotive force every point media in pipeline contribution measuring changed. which possesses one or two electrodes analyzed respectively, get law output decreases with increase area. Finally, relationship and ground diameter accounted for ratio pipe been demonstrated. This method has a certain significance research development flowmeter.
