Description

Electromagnetic flowmeter suitable for low conductivity measurement

Technical Field

The utility model mainly relates to the flowmeter field especially relates to an electromagnetic flowmeter who is suitable for low conductivity measurement

Background

The electromagnetic flowmeter has wide application in the aspects of measuring water, sewage, slurry, ore pulp, acid, alkali, salt liquid and food slurry, and has vital influence on industrial production process. The basic principle of an electromagnetic flow meter (EMF) is a Faraday electromagnetic induction law, and based on the measurement principle, the electromagnetic flow meter generally adopts an excitation technology with positive and negative polarities to avoid the polarization phenomenon of electrodes, however, when the low-conductivity fluid flow is measured, the output of the meter swings, and is unstable, so that the electromagnetic flow meter cannot be used. This phenomenon occurs because when measuring low conductivity fluids, the electrochemical potential of the electrodes changes periodically, producing a noise signal, i.e., flow noise, whose amplitude is inversely proportional to the excitation frequency. Meanwhile, when the low-conductivity liquid is measured, the self impedance of the liquid is very large, and the flow signal is very small, so that the liquid is very easily interfered by a power frequency signal of an industrial field, and further the measurement error of the flow signal is very large.
