Hygienic electromagnetic flow meter

Overview:

     The measurement principle of the LDE-W sanitary electromagnetic flow meter is based on Faraday's law of electromagnetic induction. The measuring tube of the flow meter is a non-magnetic alloy short tube lined with insulating material. The two electrodes are fixed to the measuring tube through the tube wall in the diameter direction. The electrode tip is substantially flush with the inner surface of the liner. When the exciting coil is excited by the two-wave pulse, an operating magnetic field having a magnetic flux density B is generated in a direction perpendicular to the axis of the measuring tube. At this time, if a fluid having a certain conductivity flows through the measuring tube. The LDE-W type sanitary electromagnetic flow meter can measure the flow rate of general conductive fluids in the departments of tap water, steel, petroleum, chemical, electric power, industry, water conservancy, water resources and water resources, and can also measure acid, alkali, salt, etc. Corrosive conductive liquid. Widely used in petroleum, chemical, metallurgy, textile, paper, environmental protection, food and other industrial sectors and municipal management, water conservancy construction, river dredging and other fields of flow measurement.


LDE-W type sanitary electromagnetic flowmeter features:


1. The quick link scheme is adopted, and the electromagnetic flow meter in use is convenient for quick disassembly, installation, cleaning and maintenance;


2, using 16-bit embedded microprocessor for signal processing, with fast computing speed, high calculation accuracy, full digital signal processing, strong anti-interference ability, stable and reliable measurement;


4, the new lining process and lining materials, so that the measuring tube is as clean as a mirror, no obstruction, no pressure loss, can effectively prevent the accumulation of measuring fluid residues in the measuring tube;


5. Measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure, etc.;


6. The converter adopts large-screen high-definition backlit LCD display, full Chinese character menu operation, easy to use, simple operation, and clear reading under strong light or at night;


7. The converter has a two-way automatic measurement function, which can simultaneously display measurement parameters such as flow percentage, instantaneous flow, positive and negative cumulative total;


8, the converter has a variety of output functions, current output, pulse output, RS232, RS485 digital interface, and GPRS wireless data remote transmission and other functions;


9. The converter has self-diagnosis fault alarm function, air traffic control alarm, flow upper and lower limit over limit alarm, excitation system fault detection alarm, etc.


10. The converter has a batch processing function, that is, a quantitative control function.

Selection of lining materials:

       It should be selected according to the corrosiveness, wear and temperature of the measured medium. Hard/soft rubber can resist general weak acid and alkali corrosion, temperature resistance 65 °C, soft rubber oil wear resistance, PTFE can almost resist strong acid and alkali corrosion other than phosphoric acid, medium temperature can reach 130 °C, but not abrasion. Polyurethane rubber has good wear resistance, but it is not resistant to acid and alkali corrosion, and has poor temperature resistance. The medium temperature is less than 65 ° C.
