Water flow measurement instruments insertion type electromagnetic flow meter
Advantage :
1.Measurement instruments measurement is not affected by changes in fluid pressure, temperature, viscosity,density and conductivity.
2. There are no obstructing flow parts in the measuring pipe, no pressure loss, and lower requirements for straight pipe sections , Working long life time .
3. The series of pipe diameters are DN10-DN2500. Suitable for different pipe diameters
4. The flow meter can be a two-way measurement system, with three totalizers built in, forward total, reverse total and difference total; it can display forward and reverse flow, and has a variety of outputs: current, pulse, 4-20mA,485 communication, Hart
5. Explosion-proof mag flow meter instruments can be used in corresponding explosion-proof surroundings .

Selection of lining material
Lining material |
The main performance |
The scope of application |
PTFE |
1.The most stable chemical properties of plastics in a material that is resistant to boiling hydrochloric acid,sulfuric acid and aqua regia,but also resistant to concentrated acids and various organic solvents, intolerance chlorine trifluoride, liquid oxygen, high velocity liquid oxygen, ozone corrosion. 2.Poor wear resistance |
Concentrated acid,alkali and other corrosive media |
PFA |
Corrosion resistance with PTEF,strong anti-negative pressure |
Can be used for negative pressure state |
F46 |
1.Corrosion resistance with PTEF. 2.Can withstand low wear and tear. 3.Strong anti-negative pressure. |
With PTFE 2.Can be used for low abrasive media |
Neoprene |
1. Have excellent flexibility,a high degree of tensile force,good wear resistance. 2.Resistant to the general low concentrated acid, alkali,salt medium corrosion, corrosion resistant to oxidizing media. |
3.Water, sewage, weakly abrasive mud, pulp |
Polyurethane |
1. Has excellent wear resistance (equivalent to 10 times the natural rubber). 2. acid, alkali performance is poor. 3.Do not use water mixed with organic solvents. |
Strong neutral wear pulp, coal slurry, mud and so on |
