Cement Grout concrete Magnetic Flow Meter
Description Cement Grout concrete Magnetic Flow Meter
Electromagnetic flowmeters use Faraday's law of induction to detect
flow.
Inside the electromagnetic flowmeter there is an electromagnetic
coil that generates a magnetic field, and electrodes that capture
the electromotive force (voltage). It is because of this that
electromagnetic flowmeters can measure flow when there seems to be
nothing in the pipeline.

Select the lining material
Should be based on the measured medium temperature corrosive wear
and to select the lining material
| Lining material | corrosion resistance | Working temperature | Application |
| Ne | General resistance to low concentrations of acid salt corrosion | -20～70℃ | lower industrial water effluent pH and salt concentration |
| PO | Has an excellent wear resistance, abrasion resistance slurry
dedicated to strong, not decay | -10～60℃ | Liquids containing solid particles (slurry pulp, etc.) |
| FEP | 1 corrosion resistant and quite PTFE 2 high mechanical strength, good wear resistance 3 table smooth, easy adhesion precipitate 4 have strong abrasive media fluid good resistance to outside
negative, anti-vacuum effect | -40～180℃ | except mortar. Like with PTFE can be used for drinks and other
health requirements of the media |
| PTFE | lmost all of the corrosion resistant chemical media, poor wear
resistance | -40～180℃ | Not be used for pipes and wear strong negative fluid |
