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
|
Liner material |
Main performance |
Application |
|
Neoprene |
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. |
|
PTFE |
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. |
|
PU (Polyurethane) |
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 |
|
FEP |
Chemical performance is similar with PTFE, negative pressure resisting property is better than PTFE; food degree material, price is higher. |
Same with PTFE |
|
PFA |
Chemical performance is similar with PTFE; with good negative pressure resisting property; food degree material, price is higher. |
Same with PTFE |
ELECTRODES SELECTION OF MAG FLOW METER
|
Electrodes material |
Main performance and application |
|
SUS316L |
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. |
|
HB |
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. |
|
HC |
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. |
|
Titanium |
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. |
|
Tantalum |
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. |
