Specifications
High quality water meter Electromagnetic Flow Meter 4-20mA
Product Description
Introduction
AFT Intelligent electromagnetic flow meter is a kind of high performance,high reliability of the flow meter. Used for measuring the volume flow of conducting liquid and slurry in closed conducts. Widely used in steel, electricity, petroleum, Chemical, coal, metallurgy, paper making, water supply and drainage, food, Medicine industry etc.
Feature
1. Measurement is independent of fluid density,viscosity,temperature,pressure and conductivity.
2. There are no obstacle parts in the measuring tube,no pressure loss to the tube of which the straight part is of low requirement.
3. the converter of the the LCD back light type shows and reading easily under the sun or in the dark room.
4. in bad environment parameters can be set up through the infrared ray touch nubs without opening the cover of the converter.
5. the flow meter with bidirectional measurement system, built-in three totalizer:positive total amount,
Reverse total amount and total amount difference.It shows the positive and negative flow with multiform Outputs:current, pulse, digital communication, HART.
6. the converter has alarm output function of self-diagnosis,empty load test, high and low limit of the flow,two-stage flow value,batch control of function etc.
7. Not only used in general process,but also in the test of mineral serosity,paper pulp as well as pastry liquid.
High pressure type electromagnetic flow sensor adopting PFA lining technology which is resistant to high pressure and negative pressure is specially applicable in industries of oil,chemistry etc.

Main performances |
Applications |
PTFE |
1.the most steadiest material in plastics which is resistance to boiling hydrochloric acid,vitriol and Aqua regia as well as strong and Organic Impregnates; 2.Not be perfect in abrasion resistance |
Strong corrosive mediums such as strong acid and alkali |
PFE |
Having the same abration resistance with PTFE. Having strong ability of load pressure resistance. |
Applicable in state of load pressure |
F46 |
1. Having the same abration resistance with PTFE; 2.Resistance for low abration; 3.Having strong resistance to load pressure |
1.the same as PTFE 2.Applicable in medium of low abrasion |
Neoprene |
1.Be of good elasticity,retractility and abration resistance; 2.Be resistance to low acid,alkali and salt but not for oxidation medium. |
Water,sewage and slurry, mineral serosity of low abration. |
Polyurethane |
1.Be good of abration resistibility (equal to 10 times of caoutchouc); 2.Not be perfect in acid/alkali resistance; 3.Can;t be used for water mixted with organic Impregnants |
Applicable in mineral serosity,slurry and coal slurry of high abration. |
Main performances of the electrode materials
Electrode material |
Application |
Stainless steel SUS316 |
Applicable in water,sewage and corrosive medium.Widely used in industies of petrol,chemisty,carbamide,etc |
Stainless steel covered with tungsten carbide |
Applicable in medium of no corrosive and low abration |
Hastelloy B (HB) |
Having strong resistance to hydrochloric acid of any consistence which is below boiling point.Also resistable against vitrol,phosphate,hydrofluoricacid,organic acid,alkali and non oxidable salt. |
Hastelloy C (HC) |
Be resistant to oxidable acid such as nitric acid,mixted acid as well as oxidable salt such as Fe+++,,Cu++ and sea water |
Titanium |
Applicable in seawater and kinds of chloride salt,oxidable acid(including fuming nitricacid),organic acid,alkali etc.Not resistant to a pure reducing acid(such as sulphuric acid hydrochloric acid) corrosion.but if acid contains antioxidant(such as Fe+++,Cu++) is greatly reduce corrosion. |
