Introduction 

Battery-powered 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.

Electrode material Applications
SUS316L Applicable to industrial/municipal water, wastewater and low corrosive mediums. Widely used in petroleum, chemical industries.  
Hastelloy B

 

Strong resistance to hydrochloric acids below the boiling point.

Resist against oxidable acids, alkali and non-oxidable salts. For instance, vitriol, phosphate, hydrofluoric acids, and organic acids.
Hastelloy C Exceptional resistance to strong solutions of oxidizing salts and acids. For example, Fe+++, Cu++, Nitric acids, mixed acids
Titanium

Titanium can withstand corrosive mediums such as seawater, chloride salt solutions, hypochlorite salts, oxidable acids(including fuming nitric acids), organic acids, and alkali.

Not resistant to high purity reducing acids such as sulphuric acids, hydrochloric acids. 
Tantalum

Highly resistant to corrosive mediums.

Applicable to all chemical mediums except Hydrofluoric Acids, Oleum and Alkali.
Platinum-iridium Applicable to all chemical mediums except for Ammonium salts and Fortis.
