Electromagnetic Flow meters (EMF)

Electromagnetic Flow Meter

Fluido's magnetic flow meter, also known as electromagnetic flow meter or mag meter, is widely used as it has less obstruction, cost effective and gives accurate measurement. Electromagnetic flow meters don't have any moving parts to wear own, reduciing the need for maintenance or replacement. we offer flow meters with a range of liners, electrodes, and sizes, which can meet various conductive liquids.

PERFORMANCE OF ELECTRODE MATERIAL

Electrode Material Application
SS 316 L Applicable to industrial and municipal water, wastewater and low corrosive mediums. Widey used in petroleum, chemical industries
Hastelloy C Exceptional resistance to strong solutions of oxidizing salts and acids, like Fe+++, Cu++, Nitric acids, mixed acids.
Titanium Titanium can withstand corrosive medium 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, hydrochloride acids.
Tantalum Highly resistant to corrosive mediums . Applicable to all chemical mediums except Hydrofluroic Acids, petroleum and Alkali.

PERFORMANCE OF LINEAR MATERIAL

Linear Material Application
PTFE Best Performance of linear material, chemical resistance, withstand boiling hydrochloric acid, sulphuric acid, nitric acid,alkali and vareity of organic solvents. Poor wear resistance and poor adhesion.
Hard Rubber Withstand the corrosion of hydrochloric acid, acetic acid, oxalic acid, ammonia water, phosphoric acid and 50% sulphuric acid,, sodium hydroxide, potassium hydroxide. Use of general acid, alkali, and salt solutions, not resistant to the corrosion of strong oxidants.
