Split-Type Electromagnetic Water Flowmeter (A+E 81F)
The operation of an electromagnetic flowmeter or mag meter is based upon Faraday's Law, which states that the voltage induced across any conductor as it moves at right angles through a magnetic field is proportional to the velocity of that conductor.
--Large choice of liner materials suitable for drinking water, wastewater, chemicals and other liquids.
--Suitable for use in custody transfer applications.
--Measurement is independent of the flow profile.
--Abrasion and corrosion-resistant liners available.
--Electric conductivity of medium can be used for detection of product change.
--No additional pressure loss.
--No moveable parts and long working life.
--Two-way measurement system to detect the positive and negative flow.This electromagnetic flowmeter can be used to measure the volume flow rate of conducting liquid and seriflux in closed pipes, such as pure water, sewage, all kinds of acid-alkali-salt solution, slurry, pulp, paper pulp and food liquids.
--Site LCD displays instantaneous flow, accumulative flow, flow rate.
--Various types provided according to specific conditions.

Main performances of the lining materials
1.The most steady material in plastics which is resistible to boiling hydrochloric acid, vitriol fortis as well as strong alkali and organic impregnates.
2.Not be perfect in abrasion resistance.
Strong corrosive mediums such as strong acid and alkali
1.Have the same abrasion resistance with PTFE.
2.Resistable for low abrasion.
3.Having strong resistance to load pressure.
1.The same as PTFE.
2.Applicable in mediums of low abrasion.
1.Be of good elasticity, retractility and abrasion resistance.
2.Be resistant to low acid, alkali and salt but not for oxidation mediums.
Water, sewage and slurry, mineral serosity of low abrasion.
1.Be of good abrasion resistibility.
2.Not be perfect in acid/alkali resistance.
3.Can't be used for water mixed with organic impregnants.
Applicable in mineral serosity, slurry and coal slurry of high abrasion.
Main performances of the electrode materials
Stainless steel SS316
Applicable in water, sewage and corrosive mediums. Widely used in industries of petrol, chemistry, carbamide, etc.
Having strong resistance to hydrochloric acid of any consistence which is below boiling point. Also resistible against vitriol, phosphate, hydrofluoricacid,organic acid etc which are oxidable acid, alkali and non-oxidable salt.
Be resistant to oxidable acid such as nitric acid, mixed acid as well as oxidable salt such as Fe+++,Cu++and sea water
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.
Having strong resistance to corrosive mediums that is similar with glass. Almost applicable in all chemical mediums. Except for hydrofluoric acid, oleum and alkali.
Almost be applicable in all chemical mediums except for aqua fortis, ammonium salt.
