The characteristics and working principle of electromagnetic flow meter scale

Abstract: the characteristics and working principle of electromagnetic flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Characteristics and working principle of electromagnetic flowmeter, the working principle of electromagnetic flowmeter when the conductor in magnetic field cutting lines of magnetic force movement, produces the induction electric potential in the conductor, induction electric potential and the size of the conductor in magnetic field of the length and conductor in magnetic field. More flow meter manufacturers choose model price quote you are welcome to inquire, here are the characteristics and working principle of electromagnetic flow meter scale article details. Characteristics and working principle of electromagnetic flowmeter, the working principle of electromagnetic flowmeter when the conductor in magnetic field cutting lines of magnetic force movement, produces the induction electric potential in the conductor, the size of the induction electric potential and the length of conductor in magnetic field effect and the conductor in magnetic field perpendicular to the magnetic field is directly proportional to the speed of the direction. By the same token, the conductive fluid in the magnetic field in vertical direction of flow and cut magnetic lines of force, also in the pipeline on both sides of the electrode potential is induced. The direction of the induction electric potential by the right-hand rule to judge, the size of the induction electric potential determined by the type: Ex = BDv - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Type ( 1) Ex&mdash type; Induced potential, V. B— Magnetic induction intensity, TD— Pipe diameter, mv— Average flow velocity of liquid, m/s yet qv is equal to the fluid volume flow velocity v and pipeline cross-sectional area ( π D2） / 4 of the product, the type, 1) Plug in the type: Qv = ( π D / 4 b) * Ex - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Type ( 2) By type, on the pipe diameter D has set and the magnetic induction intensity B unchanged, the measured volume flow has a linear relation with the induction electric potential. If the pipe insert a electrodes on both sides, can introduce induction electric potential Ex, to measure the electric potential, the size of the volume flow rate can be obtained. Second, the electromagnetic flowmeter performance characteristics of instrument, simple in structure, reliable, have no moving parts, long working life. No closure choke parts, there is no pressure loss and flow blocking phenomenon. No mechanical inertia, fast response and good stability, can be applied to automatic testing, adjusting and SPC system. Measurement accuracy is not affected by the type of measured medium and its temperature, viscosity, density, the influence of physical parameters such as pressure. Using ptfe or rubber lining material and the different combination of electrode material such as Hc, 316 lti can adapt to the needs of different medium. Equipped with pipeline, plug-in, such as a variety of flow meter type. Block the EEPROM memory, measuring operational data storage safe and reliable protection. Type with integration and separation of two kinds of model. High-definition LCD backlit display. A shape electromagnetic flowmeter is based on Faraday's law of electromagnetic induction, which is used to measure the volume of a conductive fluid flow. Because of its unique characteristics, has been widely used in industrial measurement of various kinds of conductive liquid. Is mainly used in chemical industry, papermaking, food, textile, metallurgy, environmental protection, water supply and drainage and other industries, and form a complete set of computer control system can be realized. 1, the electromagnetic flowmeter is a volume flow measuring instrument, in the process of measurement is not affected by the temperature of the measured medium, viscosity, density and electrical conductivity ( Within a certain range) The influence of. 2 no moving parts, electromagnetic flowmeter, nor choke, does not cause the pressure loss, also won't cause wear and tear, blocking and so on. 3, span a wide range of electromagnetic flowmeter, can amount to 1:100. In addition, the electromagnetic flowmeter is proportional to the average flow velocity of the measured medium only, and axisymmetric flow state ( Laminar or turbulent) Has nothing to do. 4, no mechanical inertial electromagnetic flowmeter, responsive, can measure the instantaneous pulse flow, and linear is good, the measured signal can be directly with the converter linear transformation into standard signal output. LD - T can be on-site instructions, LD type can be transmitted over a long distance. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
