PCB boards of Electromagnetic Flow Meter

PCB boards of Electromagnetic Flow Meter Intelligent electromagnetic flowmeter is a kind

of high performance,high precison and high

reliability flowmeter,which is widely used in

petroleum,industry,food.electricity,water

supply,paper-making and medicine industry etc

EMF8 serie electromagnetic flowmeter consisit

of the converter of EMF81,EMF86,EMF89,

EMF8E and the sensor of 01 flange type,02

holder-type,03 insertion type,05 thread-type

and 06 clamped type.

PCB boards of Electromagnetic Flow Meter

Flange type electromagnetic flowmeter consists

of the converter of EMF89,EMF81,EMF86 and

the sensor of flange type.Flange type sensor

uses the way of connecting the flange with pipe,

It has various types of electrode material and

lining material. The sensor and converter can be

combined into intergrated or split electromagnetic

flowmeter.

Flange type electromagnetic flowmeter can be

widely used not only in genaral process test,but also

in the chemical industry,water-supply,waste-water

monitoring ore pulp or paper plup etc.

Main performance of the electrode materials

MaterialCodePerformance of Corrosion Resistance
316LVUsed in industrial water,domestic water,sewage,neutral solution and the weak acid such as carbonic acid and acetic acid.
Hastelloy Alloy CHc

Oxidation resistance acid,such as nitric acid,mixed acid,complex acid mixed with sulfuric acid.Have good corrosion resistance to seawater,alkali solution and chloride solution.

Inapplicable occasion:hydrochloric acid and Hydrofluoric acid.

Hastelloy Alloy CHb

Has good corrosion resistance to non-oxidative acid,alkali,salt.

Inapplicable occasion:nitric acid.

TiTi

Have good corrosion resistance to sea water,chloride,hypochlorite and various hydroxides.

Inapplicable occasion:reducing acids like hydrochloric acid,sulfuric acid,hydrofluoric acid.

TaTa

Almost have the corrosion resistance to all chemical media,generally used for hydrochloric acid and sulfric acid.

Inapplicable occasion:hydrofluoric acid,alkali and fuming sulfric acid.

Tungsten CarbideWHave good wear resistance,used for the wearing media such as mud and paper pulp,but with poor corrosion resistance.
Platinum-iridium AloyPtBesides aqua acid and ammonium salt,almost have the corrosion resistance to all acid,alkali and salt solution.

Lining Material Selection

♦ For high-temperature media(>=140℃), preference for PFA lining

♦ For easy scaling media such as paper pulp,preference for FEP or PFA lining.

♦ For the media with sanitation requirement should select FEP(or PTEE)lining .

♦ In case of negative-pressure, should select FEP.

♦ For the wearng media such slurry and pulp should select PU or FEP lining.
