Description

TECHNICAL FIELD

[0002] Electromagnetic flowmeter is a kind of non-contact flow measuring instrument based on Faraday's law of electromagnetic induction, is widely used in the accurate measurement and control of liquid flow in industrial process. It does not need to be directly contacted with the measured medium, by measuring the induced electromotive force (i.e. potential difference) generated when conducting liquid flows in magnetic field, to indirectly calculate and display the flow of liquid.

[0003] The working principle of electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. When conducting liquid (such as water, acid-base solution, slurry, etc.) flows through a magnetic field perpendicular to the flow direction, an induced electromotive force (i.e. flow signal) proportional to the liquid flow rate will be generated on the electrodes on both sides of the pipeline. The size of this induced electromotive force is proportional to the flow rate, conductivity and magnetic field strength, and is independent of the physical parameters of the liquid such as pressure, temperature, density and viscosity. Therefore, by measuring this induced electromotive force, and combining the known parameters such as pipeline size and fluid conductivity, the instantaneous flow and cumulative flow of the fluid can be accurately calculated.
