3. Working principle of plug-in electromagnetic flowmeter

The working principle of plug-in electromagnetic flowmeter is based on Faradays law of electromagnetic induction, and its core is to calculate the flow rate by measuring the induced electromotive force generated by the movement of conductive fluid in a magnetic field.

. The following is a detailed explanation of the specific principle: Basic formula: Accordin Insertion flowmeter

g to Faradays law of electromagnetic induction, when a conductive medium (such as a liquid) cuts a magnetic induction line vertically at an average flow velocity ν, the induced electromotive force E generated between the two electrodes can be expressed as: E=B × L × ν, where: E: Induced electromotive force (unit: volt, V) B: Magnetic excitation induction intensity (unit: Tesla, T) L: Effective length of the cut magnetic induction line (unit: meter, m) ν: Average flow velocity of the fluid (unit: meter/second, m/s) The relationship between flow velocity and flow rate: When the magnetic field intensity B and effective length L are constant, the induced electromotive force E is... The flow velocity is directly proportional to. By measuring E, the average flow velocity of the fluid can be directly obtained. If the cross-sectional area A of the tested pipeline is known (which can be calculated by the inner diameter D of the pipeline, A=π D2/4), the volumetric flow rate Qv (unit: cubic meter/second, m3/s) can be expressed as: Qv=A × ν=(π D2/4) × (E/BL). After further simplification (when the insertion structure is fixed, L is related to the inner diameter D of the pipeline), the relationship between volumetric flow rate and induced electromotive force can be expressed as: Qv=K × E, where K is a constant and is related to parameters such as magnetic field strength and pipeline size. Key feature: Linear relationship: When the magnetic induction intensity B is constant, the volumetric flow rate Qv exhibits a strict linear relationship with the induced electromotive force E, making it easy to measure and calibrate. Unrelated parameters: Flow calculation is independent of physical properties such as temperature, density, and pressu
