MAG-11 Electromagnetic Flow Meter Thread Connection

Short Description:

Mag-11 Series Electromagnetic Flowmeter is based on the law of Farad Electromagnetic Induction, which is used to measure the conductance greater than 5 μS / cm volume of conductive liquids flow, such as such as water,sewage,mud,paper pulp,beverage,chemical,viscous liquid and suspension. Thread-type sensor breaks through the conventional design of electromagnetic flowmeter, it makes up the fatal flaw of some flow meters in the field of small flow measurement, it has the advantage of light and handy appearance,convenient installation,widely measuring range and hard to clogged, etc.

Electrode Material Selection

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 to:hydrochloric acid and Hydrofluoric acid
Hastelloy Alloy B	Hb	Has good corrosion resistance to non-oxidative acid,alkali,salt. Inapplicable to: nitric acid.
Ti	Ti	Have good corrosion resistance to sea water,chloride,hypochlorite and various hydroxides. Inapplicable to: 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 sulfuric acid. Inapplicable to:hydrofluoric acid,alkali and fuming sulfuric 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 Alloy	Pt	Besides aqua acid and ammonium salt,almost have the corrosion resistance to all acid,alkali and salt solution.

Lining Material Selection

1. For high-temperature media (≥140℃),preference for PFA lining.

2. For the media with sanitation requirement should select FEP(or PTFE) lining

3. For the wearing media such as slurry and pulp should select PU or FEP lining.

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

5. In the case of negative-pressure, should select FEP.

Flow Measurement Range

Each of our electromagnetic flow meter has to be tested by strict actual calibration before leaving the factory. So when you select the measuring range, generally do not violate the precondition of "range must be larger than the measured flow", and it's better for the range close to the common measured flow. Generally make the common measured flow in the range of 50% to 80%.

The measuring range of Mag series electromagnetic flow-meter can be modified according to the actual situation.

The highest velocity can reach 12m/s.
