Introduction
Electromagnetic flow meter is hallmarked by its high performance and reliability based on successful, field-proven technology. It is being widely used in industries such as petroleum, chemical engineering, iron and steel, food, electricpower, paper making, water treatment, petrochemical, medicine etc.
Features
♦ Medium temperature can be -20℃~200℃.
♦ Integrated vertification,diagnostic function and empty pipe detection.
♦ Measure forward and reverse direction flows.
♦ Built-in reference electrodes,no need to connect ground ring.
♦ Dual frequency excitation and stable zero point.
♦ Precision coil winding technology,makes magnetic field more uniform.
♦ High protection grade,IP65.
♦ No moving parts,no pressure loss.
♦ High accuracy: ±0.5% of reading,±0.3% and ±0.2% optional,velocity >0.3 m/s.
Application
♦ Chemical
♦ Medicine
♦ Beverage
♦ Iron and steel
♦ Water supply
♦ Electricpower
♦ Water treatment
Installation Notice
Installed at the lowest point and vertical upward direction Install exhaust valve at the downstreat of flow meter
Don’t install at the highest point and vertical downward diection when drop is more than 5m
Installed at the lowest point when used in open drain pipe Need 10D of upstreat and 5D of downstreat
Dont’ install it at the entrance of pump, install it at the Installed at the rising direction
exit of pump

Main performances of the electrode materials
| Electrode material |
Applications |
| sainless steel SUS316 |
Applicable in water,sewage and corrosive mediums. |
| Widely used in industries of petrol,chemistry,carbamide,etc |
|
Stainless steel covered
with tungsten carbide
|
Applicable in mediums of no corrosive and low abrasion. |
| Hastelloy B(HB) |
Having strong resistance to hydrochloric acid of any consistance which
is below bioling piont. |
| Also resistable against vitriol,phosphate, |
hydrofluoricacid,organic acid etc which are oxidable acid,alkali and
non-oxidable salt. |
| Hastelloy C(HC) |
Be resistant to oxidable acid such as nitric acid,mixed acid |
| as well as oxidable salt such as Fe+++,Cu++aStnd sea water |
| Titanium |
Applicable in seawater,and kinds of chloride,hypochlorite salt,oxidable
acid (including fuming nitric acid),organic acid,alkali etc.
|
|
Not resistant to a pure reducing acid(such as sulphuric acid,hydrochloric
acid corrosion.
|
| But if acid contains antioxidant is greatly reduce corrosion. |
| Tantalum |
Having strong resistance to corrosive mediums that is similar with glass |
| Almost is applicable to all chemical mediums. |
| Except for hydrofluoric acid,oleum and alkali. |
| Platinum-iridium |
Almost be applicable in all chemical mediums except for ammonium salt. |
