2. Measurement principle of explosion-proof electromagnetic flowmeter
The measurement principle of explosion-proof electromagnetic flowmeter is based on Faradays law of electromagnetic induction, and its core is to generate induced voltage through the interaction between magnetic field and conductive liquid, and then calculate the fluid flow rate.
. The following is a detailed explanation o
1. The basis of Faradays law of electromagnetic induction. When a conductive medium (such as a liquid) flows vertically in a magnetic field, the free charges in the medium will be displaced by the Lorentz force, resulting in induced electromotive force (voltage) at both ends of the medium.
. The magnitude of induced electromotive force is proportional to the magnetic flux density (B), the inner diameter of the measuring tube (D), and the average flow velocity of the liquid (V). The formula is: E=B × D × V, where E: induced electromotive force (flow signal); B: Magnetic field strength (generated by electromagnetic coils); D: Measure the inner diameter of the tube; V: Average axial flow velocity of liquid2. Structure design of explosion-proof electromagnetic flowmeter Magnetic field generation: A constant magnetic field is generated through electromagnetic coils at the upper and lower ends, with the magnetic field direction perpendicular to the fluid flow direction. The function of conductive medium: The conductive liquid inside the measuring tube is equivalent to a conductive metal rod in Faradays experiment. When it flows through a magnetic field, it cuts magnetic induction lines and generates induced voltage. Electrode measurement: Two electrodes installed on the inner wall of the pipeline are used to detect induced voltage, and the voltage signal is amplified and converted into flow data. Electromagnetic isolation: The inner lining of the measuring tube is made of non-conductive materials (such as rubber, Teflon) to ensure electromagnetic isolation between the fluid, electrodes, and pipeline, avoiding signal interference. 3.
