QTLD magnetic flow meter, also known as electromagnetic flow meter or mag meter, is widely used because less obstruction, cost-effective and accurate measurement. Electromagnetic flow meter don’t have any moving parts to wear down, reducing the need for maintenance or replacement. Flowmeters are available with a variety of inserts, electrodes and sizes to suit different conductive fluids.

Main Performance of Electrode Material
| Electrode Material | Application |
| SS316L | Applicable to industrial and 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, like vitriol,phosphate, hydrofluoric acids and organic acids. |
| Hastelloy C | Exceptional resistance to strong solutions of oxidizing salts and acids, like 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. |
Main Performance of Liner Material
| PTFE | Best chemical resistance, withstand boling hydrochloric acid, sulfuric acid,nitric acid, alkali and a variety of organic solvents. Poor wear resistance and poor adhesion. |
| PFA | Highly resistant to chemicals Performance well under vacuum pressure condition. |
| Neoprene | Excellent elasticity, good abrasion resistance. Withstand the corrosion of low-concentration acid, alkali, salt and other media. Not resistant to corrosion by oxidizing medium. |
| Polyurethane | Strong abrasion resistant, applicable for slurries and muds. Poor corrosion resistance, can’t be used for corrosive medium. |
| Hard Rubber | Withstand the corrosion of hydrochloric acid, acetic acid, oxalic acid, ammonia water, phosphoric acid and 50% sulfuric acid, sodium hydroxide, potassium hydroxide. Use for general acid, alkali, and salt solutions, not resistant to the corrosion of strong oxidants. |
