High Accuracy Water Electromagnetic Flow Meter

  Introduction and Application High accuracy water electromagnetic flow meter is hallmarked by its high performance and reliability based on successful, field-proven technology. It is being widely used in industries such as petroleum, chemical engineering, iron and steel, food, electricpower, paper making, water treatment, petrochemical, medicine etc. Features Measurement depends on fluid density, humidity, temperature, pressure and conductivity. There is no obstructive in the conduit and no pressure drop, and the straight pipe required is relatively short. The sensor is equipped with the advanced processing technology that provides excellent immunity to negative pressure. LCD display of the converter makes it easy to read during daylight and in darkness. Parameters can be set up using infrared touch nubs no need to open the cover of the converter. Automatic alarm functions for selfdiagnosis, empty load test, high and low limit of flow, two-stage flow value, etc. It is applicable not only to general process, but also in tough applications such as mining, papermaking, pastry, etc. High pressure sensor with PFA liner is resistant to high pressure and negative pressure, and available to chemistry and corrosive solution.           Technical Performance Parameters Model DN6~DN3000mm Nominal Pressure 0.6~1.6MPa(2.5Mpa/4.0Mpa/6.4Mpa...42Mpa) Accuracy ±0.5%,±0.3%or±0.2% are selectable Liner material Teflon,PFA,F46,Neoprene,Polyurethane Electrode Type General type ,scraper type and replaceable type Electrode material Stainless steel SUS316,Hastelloy C,Titanium,Tantalum Platinumiridium, Stainless steel covered with tungsten carbide Mediem temperature Integrate type -20°C~+60°C Remote type Neoprene & Polyurethane Liner -10°C~+80°C  PTFE Liner /PFA Liner /F46 Liner -10°C~+160°C Ambient Temperature -25°C ~+ 60°C Ambient Humidity  5~100%RH(relative humidity) Medium Electrical  conductivity ≥5μ s/cm Measuring Range 1500:1,flow rate<15m/s Structure type  Integral type,remote type,submersible type,ex-proof type Protection Class IP65,IP68(optional) Ex-proof Mark ExmdⅡT6 Product Standard JB/T 9248-1999 Electormagnetic Flowmeter Main performances of the electrode materials Electrode material Applications sainless steel SUS316 Applicable in water,sewage and corrosive mediums. Widely used in industries of petrol,chemistry,carbamide,etc Stainless steel covered with tungsten carbide Applicable in mediums of no corrosive and low abrasion. Hastelloy B(HB) Having strong resistance to hydrochloric acid of any consistance which  is below bioling piont. Also resistable against vitriol,phosphate, hydrofluoricacid,organic acid etc which are oxidable acid,alkali and  non-oxidable salt. Hastelloy C(HC) Be resistant to oxidable acid such as nitric acid,mixed acid as well as oxidable salt such as Fe+++,Cu++aStnd sea water Titanium Applicable in seawater,and kinds of chloride,hypochlorite salt,oxidable acid (including fuming nitric acid),organic acid,alkali etc. Not resistant to a pure reducing acid(such as sulphuric acid,hydrochloric  acid   corrosion. But if acid contains antioxidant is greatly reduce corrosion. Tantalum Having strong resistance to corrosive mediums that is similar with glass Almost is applicable to all chemical mediums. Except for hydrofluoric acid,oleum and alkali. Platinum-iridium Almost be applicable in all chemical mediums except for ammonium salt.   VELOCITY-FLOW RATE TABLE Pipe Size Min.Flow Rate (0~0.5m/s) Min.Flow Rate (0~10m/s) mm inch L/min,m3/h L/min,m3/h 10 3/8 0 ~ 2 L/min 0 ~ 40 L/min 15 1/2 0 ~ 5 L/min 0 ~ 100 L/min 20 3/4 0 ~ 7.5 L/min 0 ~ 150 L/min 25 1 0 ~ 10 L/min 0 ~ 200 L/min 32 1.25 0 ~ 20 L/min 0 ~ 400 L/min 40 1.5 0 ~ 30 L/min 0 ~ 600 L/min 50 2 0 ~ 3 m3/h 0 ~ 60 m3/h 65 2.5 0 ~ 6 m3/h 0 ~ 120 m3/h 80 3 0 ~ 9 m3/h 0 ~ 180 m3/h 100 4 0 ~ 12 m3/h 0 ~ 240 m3/h 125 5 0 ~ 21 m3/h 0 ~ 420 m3/h 150 6 0 ~ 30 m3/h 0 ~ 600 m3/h 200 8 0 ~ 54 m3/h 0 ~ 1080 m3/h 250 10 0 ~ 90 m3/h 0 ~ 1800 m3/h 300 12 0 ~ 120 m3/h 0 ~ 2400 m3/h 350 14 0 ~ 165 m3/h 0 ~ 3300 m3/h 400 16 0 ~ 225 m3/h 0 ~ 4500 m3/h 450 18 0 ~ 300 m3/h 0 ~ 6000 m3/h 500 20 0 ~ 330 m3/h 0 ~ 6600 m3/h 600 24 0 ~ 480 m3/h 0 ~ 9600 m3/h 700 28 0 ~ 660 m3/h 0 ~ 13200 m3/h 800 32 0 ~ 900 m3/h 0 ~ 18000 m3/h 900 36 0 ~ 1200 m3/h 0 ~ 24000 m3/h 1000 40 0 ~ 1350 m3/h 0 ~ 27000 m3/h
