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.
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
Material | Code | Performance of Corrosion Resistance |
316L | V | Used in industrial water,domestic water,sewage,neutral solution and the weak acid such as carbonic acid and acetic acid. |
Hastelloy Alloy C | Hc | 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 C | Hb | Has good corrosion resistance to non-oxidative acid,alkali,salt. Inapplicable occasion:nitric acid. |
Ti | Ti | Have good corrosion resistance to sea water,chloride,hypochlorite and various hydroxides. Inapplicable occasion:reducing acids like hydrochloric acid,sulfuric acid,hydrofluoric acid. |
Ta | Ta | 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 Carbide | W | Have good wear resistance,used for the wearing media such as mud and paper pulp,but with poor corrosion resistance. |
Platinum-iridium Aloy | Pt | Besides 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.
