1 WP-MF-/(integrative /split) universal type electromagnetic flow meter MF- split type MF- integrative type MF- integrative type Product applicability lectromagnetic flow meter is constitut by the primary and the converter two parts, based on faraday s laws of electromagnetic induction carry on work, use to measure the electric conductivity liquid or two phase medium for which required electric conductivity generally must more than 5 μs/cm (original electric conductivity of the running water about is 100~500μs/cm ), can be used to metering various acid alkali brine solution paper pulp ore pulp medium etc., but can not include more ferromagnetic substance and considerable air bubbl in them. lectromagnetic flow measurement for many industry department such as petroleum chemical industry metelargy light and textile industry papermaking environment protection food etc. and municipal management water projects construction field etc. Working principle The metering system of the electromagnetic flow meter primary is base on Faraday s laws of electromagnetic induction, on the channel border which is vertical each other with metering tube axis and line of magnetic field mount one pair detecting electrode, when the conductive liquid move alon metering tube axis conductive liquid cutting the line of magnetic field induce the inductive.m.f. This MF detect out by two electrodes on the metering tube, numerical value size is: Here: inductive MF; K instrument constant; magnetic induction V average flow velocity in metering tube section; metering tube inner diameter; =KV When measure flow rate fluid flow through magnetic field which is vertical to flow direction, conductive liquid movement induce one MF in direct proportion to average flow velocity, so that require measured flow liquid have higher than lowest limit conductivity. Its induction voltage signal is detected by two electrodes, and pass through a cable transmit to converter, after through signal treatment and correlative operation, take the integrating flow and the instantaneous delivery indicate on the display screen of the converter.

2 Instrument characteristic 1.1 In metering tube have not flow resistance and movable component therefore can not cause extra energy loss also can not cause stop up, so that its energy saving effect is remarkable. special suit to measure liquid solid two phase flow such as sewage slurry ore pulp water-coal pulp paper pulp and so on. 1.2 Of contact with measured medium only have liner and electrode, as long as reasonably select liner and electrode material it can attain good non-corrodibility and wear ability, so that can measure various acid and alkali etc. chemical solution. 1.3 Installation demand is low. straight upstream section only need 5 and downstream section is 2 ( is inner diameter of selected instrument). 1.4 Measurement accuracy non-subject the influence of fluid density viscosity temperature pressure and conductivity variation, also can measure positive / negative two directional flow rate, thus is has provided the very good means for precise measurement of flow rate. 1.5 Instrument watt consumption is small, lower than 5V. 1.6 onverter have good changeability, need not renew real flowing calibration can gain measurement accuracy. ecause the electromagnetic flow meter have a serial strong point, so that it in various industry gain the more the wide application, become a first choice instrument of liquid flow measurement.

5 Selection of electrode material User is responsible for selection which must according to corrosiveness of measured medium. For general medium, user can refer to the anti-corrosion manual. When choosing electrode material, user must do experiments about medium with complex ingredient. lectrode material 1r18Ni9Ti Or18Ni12Mo2Ti H H Ti Ta orrosion-proof performance It has anti-corrosion effect on medium, such as nitric acid, phosphoric acid and other cold inorganic acid, solution with alkali and salt, organic acids, seawater and so on. When it encounter medium, such as vitriol, hydrochloric acid, hydrofluoric acid, boiling formic acid, boiling oxalic acid, chromic acid industry, as well as sodium and chlorine, bromine and iodine, it has poor chemical stability. Therefore, it adapts to non-corrosion or poor-corrosion medium, such as water, sewage, ore magma, slop, fiber slurry, syrup and other fluid. It has anti-corrosion effect on medium, such as nitric acid, vitriol less than 5% at room temperature, boiling phosphoric acid, formic acid, aqueous alkali, sulfurous acid under a certain pressure, seawater, acetic acid and so on. It can be widely used in petrochemical, urea, vinylon and other industries. It can resist corrosion from all concentration of hydrochloric acid under boiling point; as well as vitriol, phosphoric acid, organic acids and other non-oxidizing acids, alkali, non-oxidizing salt liquid. It can resist corrosion from oxidizing acid, such as nitric acid, chromic acid or vitriol, and other mixed acid. It also can resist corrosion from oxidizing salt, such as Fe++, u++ or other oxidants, hypo-argon hydrochloric acid solution that above normal temperature, and grease. It can resist corrosion from grease, various chloride salt and sub-chloride, oxidizing acid (including fuming vitriol, nitric acid), organic acid, alkali and so on. It cannot resist corrosion from pure reducing acid (such as vitriol, hydrochloric acid); but if acid with hydrogenated agent, the corrosion reduce. It has well anti-corrosiveness, similar to glass. It can resist corrosion from almost any chemical medium expected hydrofluoric acid, oleum and alkali. Selection of lining material Selection must according to corrosiveness, wearability and temperature of the measured medium. Neoprene can resist general weak acid, alkaline corrosion and temperature of 80 ; has wear resistance. PTF almost can resist strong acid, alkaline corrosion, heat-phosphate excepted. Medium temperature can reach 180, but not has wear resistance. Urethane rubber has better wear resistance, but not resists acid and alkaline corrosion; has poor temperature resistance. Medium temperature below 65. Lining material PTF, F4 haracteristics of lining material and applicability Main characteristics 1. It is one of the most stable chemical properties plastic materials.
