Widely used in petroleum, chemical industries. Hastelloy B Strong resistance to hydrochloric acids below the boiling point. Resist against oxidable acids, alkalis and non-oxidable salts. For instance, vitriol, phosphate, hydrofluoric acids, and organic acids. Hastelloy C Exceptional resistance to strong solutions of oxidizing salts and acids. For example, Fe , Cu , Nitric acids, mixed acids Titanium Titanium can withstand corrosive mediums such as seawater, chloride salt solutions, hypochlorite salts, oxidable acids(including fuming nitric acids), organic acids, and alkalis. Not resistant to high purity reducing acids such as sulphuric acids, hydrochloric acids. Tantalum Highly resistant to corrosive mediums. Applicable to all chemical mediums except Hydrofluoric Acids, Oleum and Alkali. Platinum-iridium Applicable to all chemical mediums except for Ammonium salts and Fortis Table 3: Battery Powered Electromagnetic Flow Meter Flow Range Size Flow Range & Velocity Table （mm） 0.1m/s 0.2m/s 0.5m/s 1m/s 4m/s 10m/s 12m/s 15m/s 3 0.003 0.005 0.013 0.025 0.102 0.254 0.305 0.382 6 0.01 0.02 0.051 0.102 0.407 1.017 1.221 1.526 10 0.028 0.057 0.141 0.283 1.13 2.826 3.391 4.239 15 0.064 0.127 0.318 0.636 2.543 6.359 7.63 9.538 20 0.113 0.226 0.565 1.13 4.522 11.304 13.56 16.956 25 0.177 0.353 0.883 1.766 7.065 17.663 21.2 26.494 32 0.289 0.579 1.447 2.894 11.575 28.938 34.73 43.407 40 0.452 0.904 2.261 4.522 18.086 45.216 54.26 67.824 50 0.707 1.413 3.533 7.065 28.26 70.65 84.78 105.98 65 1.19 2.39 5.97 11.94 47.76 119.4 143.3 179.1 80 1.81 3.62 9.04 18.09 72.35 180.86 217 271.3 100 2.83 5.65 14.13 28.26 113.04 282.6 339.1 423.9 125 4.42 8.83 22.08 44.16 176.63 441.56 529.9 662.34 150 6.36 12.72 31.79 63.59 254.34 635.85 763 953.78 200 11.3 22.61 56.52 113.04 452.16 1130.4 1356 1696 250 17.66 35.33 88.31 176.53 706.5 1766.25 2120 2649 300 25.43 50.87 127.2 254.34 1017 2543.4 3052 3815 350 34.62 69.24 173.1 346.19 1385 3461.85 4154 5193 400 45 90 226.1 452 1809 4522 5426 6782 450 57 114 286.1 572 2289 5723 6867 8584 500 71 141 353.3 707 2826 7065 8478 10598 600 102 203 508.7 1017 4069 10174 12208 15260 700 138 277 692.4 1385 5539 13847 16617 20771 800 181 362 904.3 1809 7235 18086 21704 27130 900 229 458 1145 2289 9156 22891 27469 34336 1000 283 565 1413 2826 11304 28260 33912 42390 1200 407 814 2035 4069 16278 40694 48833 61042 1400 554 1108 2769 5539 22156 55390 66468 83084 1600 723 1447 3617 7235 28938 72346 86815 108518 1800 916 1831 4578 9156 36625 91562 109875 137344 2000 1130 2261 5652 11304 45216 113040 135648 169560 2200 1368 2736 6839 13678 54711 136778 164134 205168 2400 1628 3256 8139 16278 65111 162778 195333 244166 2600 1910 3821 9552 19104 76415 191038 229245 286556 2800 2216 4431 11078 22156 88623 221558 265870 332338 3000 2543 5087 12717 25434 101736 254340 305208 381510 Remark:Suggest flow velocity range 0.5m/s – 15m/s Table 4: Battery Powered Electromagnetic Flow Meter Selection GuideBattery Powered Electromagnetic Flow Meters | RWEM/D RWEM/D X X X X X X X X X Caliber size DN10-DN2000 (3/8″-80″) Structure Compact 1 Remote 2 Lining Material PTFE 1 FEP 2 PFA 3 Neoprene 4 Polyurethane 5 Hard Rubber 6 Ceramic 7 Others 8 Electrode Material SS316L 1 Hastelloy B 2 Hastelloy C 3 Titanium 4 Tantalum 5 Platinum-iridium 6 Stainless steel covered with tungsten carbide 7 Others 8 Sensor Material Carbon Steel 1 SS304 2 SS316 3 Power Supply 3.6 V lithium battery 1 3.6 V lithium battery and 12~24 VDC 2 3.6 V lithium battery and 85~265 VAC 3 Signal Output /Communication None N Pulse P RS485 R GPRS G 4~20 mA (need external power) 4 Process Connection SANS SA10:PN10, SA16:PN16, SA25:PN25, SA40:PN40 S** Flange DIN D10: PN10, D16: PN16, D25: PN25, D40: PN40 D** ANSI A15: 150#, A30: 300#, A60: 600# A** JIS J10: 10K, J20: 20K, J30: 30K J** Others O Insertion G2″ thread ball valve IT DN50 flange ball valve IF Tri-clamp TC Wafer W Thread T Measuring Mode Flow 1 Flow Temperature 2 Flow Pressure 3
