2. Features and applications:
magnetic flow meters for water is an instrument that measures the flow of conductive liquids based on the principle of Faraday’s law of electromagnetic induction. When the conductive liquid flows in the pipe, it cuts the magnetic field lines in the vertical direction, and an induced electric potential is generated on the electrodes on both sides of the pipe. The magnitude of the induced potential is proportional to the average flow rate of the conductive medium inside the pipe. The magnitude of the induced potential is transmitted to the converter, and the converter calculates the clockwise flow rate and the cumulative flow rate.
⑴. There are no resisting parts in the pipeline, the pressure loss is very small, the measurable flow range is large, the ratio of the maximum flow rate to the minimum flow rate is generally more than 20:1, and the applicable industrial pipe diameter range is wide, up to 3m.
⑵. The output signal is linear with the measured flow rate and has high accuracy. It can measure the flow rate of all conductive liquids such as acids, alkalis, salt solutions, water, sewage, corrosive liquids, mud, mineral pulp, paper pulp, etc. with conductivity ≥5μs/cm. .

4.Selection of electrodes material
| Electrode material | Corrosion resistance |
SUS316 | For industrial water, domestic water, sewage, corrosive media, widely used in petroleum, chemical, urea, and other industries. |
Stainless steel coated tungsten carbide | For non-corrosive, highly abrasive media |
Tantalum (Tan) | Has excellent corrosion resistance, and the glass is very similar, in addition to hydrofluoric acid, fuming nitric acid, alkali, almost all chemical media (including hydrochloric acid, sulfuric acid and aqua regia) corrosion. |
Titanium(Ti) | It is resistant to seawater, various chlorides and hypochlorites, oxidative acids (including fuming nitric acid), organic acids, alkalis, etc, and is not resistant to the corrosion of pure reducing acids (such as sulfuric acid and hydrochloric acid). However, if the acid contains oxidants (such as nitric acid, Fe +++, Cu ++), the corrosion is greatly reduced. |
Hastelloy C(HC) | Oxidative acid, such as nitric acid, mixed acid or chromic acid and sulfuric acid mixed medium corrosion, but also resistant to oxidizing salts such as Fe +++, Cu ++ or other oxidants such as hypochlorite solution above sea level, sea water corrosion |
Platinum – iridium alloy | Almost applies to all chemicals, but not aqua regia and ammonium salts. |
Hastelloy B(HB) | Hydrochloric acid of all concentrations below the boiling point has good corrosion resistance, but also sulfuric acid, phosphoric acid, hydrofluoric acid, organic acids and other non-oxidizing acid, alkali, non-oxidizing salt solution corrosion. |
