FLEM Electromagnetic Flowmeter Order Information

Instrument Selection

CeYeKo FLEM flowmeter following Faraday’s Law, magnetic flowmeter can be adapted for sanitary uses. They have large line sizes available. No pressure drop induced. Dirty liquids and even slurries OK. On the other hand, magnetic flowmete cann’t work on nonconductive fluids or the fluids conductive range less than 5μS/cm, such as oils deionized water and boiler feed water. Steam or gas flows don’t register.

Selection of Lining

How to Choose the Lining Materials
Lining materialMain PerformanceApplications
Teflon1.The most steady material in plastics which is resistibal to boiling hydrochloric acid, vitriol and aqua 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
PFAHaving the same abrasion resistance with PTFE.
Having strong ability of load pressure resistance.		Applicable in state of load pressure
F461. 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.
Neoprene1. Be of good elasticity, retractility and abrasion resistance.
2. Be resistant to low aicd, alkali and salt but not for oxidation mediums.		Water, sewage and slurry, mineral serosity of low abrasion.
Polyurethane1. Be of good abrasion resistibility.
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 of high abrasion.

Selection of Electrode

How to Choose the Electrode Materials
Electrode materialApplications
Stainless steel SUS316Applicable in water,sewage and corrosive mediums.Widely used in industries of petrol, chemistry, carbamide, etc…
Stainless steel covered with tungsten carbideApplicable in mediums of no corrosive and low abrasion.
Hastelloy B(HB)Having strong resistance to hydrochloric acid of any consistance which is below boiling piont. Also resistable against vitriol, phosphate, hydrofluoric acid, organic acid etc… which are oxidable acid, alkali and non-oxidable salt.
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.
TitaniumApplicable in sea water, 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 Fe3+, Cu2+) is greatly Reduce corrosion.
TaIn addition to hydrofluoric acid, fuming sulfuric acid, alkali remaining outside chemicals, including boiling hydrochloric acid
Platinum-iridiumAlmost be applicable in all chemical mediums except for aqua fortis, ammonium salt.
