Product Description
Working principle
Electromagnetic flow meters detect flow by using Faraday's Law of induction.
Inside an electromagnetic flow meter, there is an electromagnetic coil that generates a magnetic field, and electrodes that capture electromotive force(voltage). Due to this, although it may appear as if there is nothing inside the flow pipe of an electromagnetic flow meter, flow can be measured.Under Faraday's law of induction, moving conductive liquids inside of a magnetic field generates an electromotive force (voltage) in which the pipe inner diameter, magnetic field strength, and average flow velocity are all proportional. In other words, the flow velocity of liquid moving in a magnetic field is converted into electricity.
E= K B V D

Where:
E—induced electromotive force; D—measuring tube diameter;
B—magnetic induction intensity; V— average velocity;
K—it is a coefficient that relates to the field distribution and axial length;
B—magnetic induction intensity; V— average velocity;

Lining materials
Electrode materials include 316L electrode, tantalum electrode, HC electrode, platinum electrode, etc.The magnetic flow meter should choose electrode materials according to corrosiveness of the measured fluid. See the table below and there are some common electrode materials and its applications.
Lining Materials | Main Performance | Applications |
Teflon (PTFE/F4) | 1. The most steady material in plastics which is resistible to boiling hydrochloric acid, sulfuric acid, aqua regia,as well as strong alkali and organic solutions. 2. Not perfect in abrasion resistance. | Applicable in strong corrosive fluids such as strong acid and alkali. |
PFA (Perfluoroalkoxy) | 1. The same abrasion resistance as PTFE. 2. Having strong ability of load pressure resistance. | Applicable in state of strong load pressure. |
F46 | 1. The similar corrosion resistance to acid, alkali, and salt with PTFE. 2. Better resistance to abrasion and load pressure than PTFE. | Same applications as PTFE. |
Neoprene (chloroprene rubber/CR) | 1. Good elasticity, retractility and abrasion resistance. 2. Resistance to corrosion of low aicd, lkali and salt but not for oxidation media. | Water, sewage, sea water and slurry, mineral serosity with low abrasion. |
Polyurethane | 1. Good abrasion-resistance performance. 2. Not be perfect in acid/alkali resisitance. 3. Can't be used for water mixed with organic impregnants. | Applicable in mineral serosity, slurry and coal slurry with high abrasion |
Electrode materials
Electrode materials include 316L electrode, tantalum electrode, HC electrode, platinum electrode, etc.The magnetic flow meter should choose electrode materials according to corrosiveness of the measured fluid. See the table below and there are some common electrode materials and its applications.
Electrode material | Applications |
Stainless 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 |
Hastelloy C(HC) | Be resistant to oxidable acid such as nitric acid,mixed acid as well as oxidable salt such as Fe+++,Cu++and 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(such as Fe+++,Cu++)is greatly reduce corrosion. |
Ta | Other chemical media except hydrofluoric acid, fuming sulfuric acid and alkali, including boiling point hydrochloric acid, nitric acid and sulfuric acid <175℃. |
Platinum-iridium | Almost be applicable in all chemical mediums except for aqua fortis,ammonium salt. |
