Influence of Magnetic Admixtures over Information Signal of Electromagnetic Flowmeter
AbstractMagnetic admixtures distort distribution of magnetic field and virtual current in active zone of electromagnetic flowmeter therefore information signal of electromagnetic flowmeter is changed. By analogy between electrostatic, magnetic and electric current fields the error of measurement is calculated. The error of measurement depend on the form and the conductivity of admixtures. If the conductivity of admixtures is good and they form is near of sphere the error of measurement may amount to 6c (c – relative volume concentration of admixtures). There is can to decrease the error of measurement if the magnetic stream is stabilized in active zone of electromagnetic flowmeter.
