DN100 Battery powered RS485 Electromagnetic Flowmeter

 

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 of the liner materials   

Liner material	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.
Tantalum	Having strong resistance to corrosive mediums that is similar with glass.Almost applicable in all chemical mediums except for hydrofluoric acid,oleum and alkali.
Platinum-iridium	Almost be applicable in all chemical mediums except for aqua fotis,ammonium salt.

Display 

There line display:Using 120 segments of bit code displays,may realize the flow velocity,flow,and the amount of information,billing,alarm information,the battery power etc other data,information display. Display content can choose,the use of magnetic spring switch without operation identity authentication of showing,the contents of the switch can be realized.

 

the internal accumulative total calculators

for forward flow,reverse flow gross amount and net amount,and can realize eight accumulation

 

Programming

If in order to provide data to the company,the product of relevant data in the interior of the converter for programming good before leave the factory.If necessary,it is using the communication interface of the upper or authorized by the user to cover of the operator by instrument pane key easy to realize the converter to programming,and will not affect converter technical performance.
