Electromagnetic Flow Meter for Water Treatment With Reasonable
WFD electromagnetic flowmeter, composed of sensor and converter,
works based on Faraday's law of
electromagnetic induction. It is used to measure
electricalconductivity of liquid or solid. Generally, the
conductivity should be over 5uS/cm (electrical conductivity of tap
water, raw water is about 100-500uS/cm. It
can also be used to measure various mediums like acid, alkali,
saline solution, paper pulp, ore pulp
and so on, but these mediums can't contain a lot of magnetic
materials and bubbles.

Main performances of the electrode materials
Applicable in water,sewage and corrosive mediums.
Widely used in industries of petrol,chemistry,carbamide,etc
covered with tungsten
Applicable in mediums of no corrosive and low abrasion.
Having strong resistance to hydrochloric acid of any consistance
which is below bioling piont.Also resistable against
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++aStnd sea water
Applicable in seawater,and kinds of chloride,hypochlorite
(including fuming nitric acid),organic acid,alkali etc.
Not resistant to a pure reducing acid(such as sulphuric
But if acid contains antioxidant is greatly reduce corrosion.
Having strong resistance to corrosive mediums that is similar with
Almost is applicable to all chemical mediums.
Except for hydrofluoric acid,oleum and alkali.
Almost be applicable in all chemical mediums except for ammonium
