电磁流计

Electromagnetic Flow Meter PrincipleThe basic principle of electromagnetic flow meter is Faraday law of electromagnetic induction. When the conductor carried out the running of cutting magnetic force line in the magnetic field, the induced electromotive force will be produced in the conductor. Our products are widely used in the accurate flow of sewage, paper pulp, mud, slurry and so on.AdvantagesFor harsh operating condition, such as high concentration slurry or low electrical conductivity fluid, it may realize high-accuracy and stable measurement.The measurement is not affected by the fluid density, viscosity, temperature and pressure change.No components stopping flowing in the pipe; Small pressure drop; Maintenance-free; Low requirement to the straight pipe sectionGrounded electrode to realize good grounding of meter.Full digital processing; Strong anti-interference capability;Double flow direction measurement, double direction accumulating function.4-20mA / Pulse / RS485 / HART / Profibus communication Technical parameters Sensor SizeDN3-DN2000Pressure0.6-4.0 MPa, high pressure custom-madeFlange materialCarbon steel: stainless steelLining materialRubber, PTFE, PFAElectrode material316L, 904L,Hb, Hc, titanium, tantalum, platinum – iridiumGrounding electrode(ring)materialSS316,SS316L, Hb, Hc, titanium, tantalum, platinum – iridiumElectrical conductivity≥5μS/cmMedium temperature-40 +180 (PTFE/PFA lining),-25 +65 (rubber lining)ProtectionIP67, IP68Ex-proofExd[ia]iamIICT5Transmitter Power source24VDC / 220VAC 50HzSignal output4-20mA, frequency output,pulse outputPower consumption≤10W (AC power supply); ≤6W (DC power supply)DisplayLCD,instant and accumulationAmbient conditionAmbient temperature: -20 60 ; relative humidity: 5% 90%Accuracy±0.5% ( standard), ±0.2% (high accuracy )Repeatability±0.2%Measuring rangeRecommended range of use: 0.3m/s-10m/s continuous adjustablemaximum range of use: 0.01m/s-15m/s continuous adjustableCommunication modeHart communication (optional), RS485 communication (optional)or Profibus DP/PA FFProtectionIP67 / IP68Ex-proofExd[ia]iamIICT5Electrical interfaceM20×1.5 / 1/2 NPTBody materialCast aluminum
