CHARACTERS OF MAGNETIC FLOW METER
1. Measuring accuracy will not be influenced by medium temperature, pressure, viscosity, density and physical parameter; as long as the conductivity of measured medium more than 20μs/cm, and indication will not be influenced by conductivity changes.
HOW TO CHOOSE LINER OF MAGNETIC FLOWMETER
Good elasticity and high breaking tenacity,good wearing resistance performance; resist common concentrated acid,alkali and salt.
1.Max temperature of medium is 80C;2.mainly used to measure water, sewage, slurry and pulp etc.
The chemical performance of PTFE is the most stable in all plastics, and resist boiled hydrochloric acid, sulfuric acid,nitric acid aqua regia, concentrated alkaline and kinds of organic solutions; food degree material.
Temperature of medium: -40C to 180C;mainly used to strong corrosive medium like concentrated acid, alkali and sanitary medium.
With excellent wear resisting property(equals to ten times of natural rubber);but bad acid and alkali resisting property;
Max temperature of medium should be less than 80C; used to measure pulp and coal slurry with middle strong abrasion
Chemical performance is similar with PTFE, negative pressure resisting property is better than PTFE; food degree material, price is higher.
Same with PTFE

ELECTRODES SELECTION OF MAG FLOW METER
Main performance and application
Used to industrial water, life water and sewage etc, with weak corrosion performance; apply to petroleum, chemical, metallurgy industries, and municipal and environmental protection fields.
With good corrosion resistance performance to all concentrations of hydrochloric acid below the boiled point; also resist sulfuric acid, phosphoric acid, hydruoric acid, organic acid and other non-oxidizing acid, alkali and hydrochloric acid etc.
Resist non-oxidizing acid, such as the mixture of nitric acid/chromic acid and sulfuric acid; and resist oxidizing salt, such as Fe3+,Cu2+ and other oxidizing agents like hypochlorite solution and sea water etc.
Resist sea water, kinds of chlorides, hypochlorite, oxidizing acid (including introsonitric acid). organic acid and alkali etc, but do not resist purified reductic acid (sulfuric acid, hydrochloric acid); Corrosion will reduce greatly when it has only oxidzing agent(like nitric acid and ionic mediums with Fe, Cu ) in the acid.
Good corrosion resistant property, which is similar with glass; it could almost resist all chemical mediums (including boiling hydrochloric acid, nitric acid and sulfuric acid below 175C), but do not resist hydrofluoric acid, strong sulfuric acid and alkali.
Stainless steel coated with tungsten carbide
Used to strong wearing mediums without corrosion.
