| Abstract: | The method of square wave field and interpolation can not only efficiently eliminate the transformer AC disturbance voltage in the magnetic-inductive flowmeter with AC field, but also efficiently reduce the influences of the electrochemical DC disturbance voltage and its change in the magnetic-inductive flowmeter with DC field. Therefore this method can greatly improve the measuring precision of the magnetic-inductive flowmeter. |
