Introductions
Electromagnetic flow meter consists of sensors and converters in two parts.
The product is based on Faraday’s law of electromagnetic induction, used to measure the conductance greater than 20 μS / cm volume of conductive liquid flow, In addition to measuring the general volume of conductive liquid flow, but also can be used to measure strong acid, alkali and other strong corrosive liquids and mud, pulp, pulp and other liquid-solid two-phase suspension of uniform volume flow.

Electrode Property
| SS316L | Applicable in water,sewage and corrosive mediums.Widely used in industries of petrol,chemistry,carbamide,etc |
| Stainless Steel Coveredwith tangsten carbide | Applicable in mediums of no corrosive and low abrasion. |
| Hastelloy B | 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 | Be resistant to oxidable acid such as nitric acid,mixed acid as well as oxidable salt such asFe+++,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.Acid contains antioxidant(such as Fe+++,Cu++)will greatlyreduce corrosion. |
| Tantalum | Having strong resistance to corrosive mediums that is similar with glass. Almost applicable in allchemical mediums.Except for hydrofluoric acid,oleum and alkali. |
