Summary
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
Measurement is independent of fluid density,viscosity,temperature ,pressure and conductivity.
There are no obstacle parts in the measuring tube ,no pressure loss to the tube of which the straight part is of low requirement.
The converter of the the LCD back light type shows and can be read easily under the sun or in the dark room.
In bad environment parameters can be set up through the infrared ray touch nubs without opening the cover of the converter.
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.
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.
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.
Operation Principle
The method of measurement is based on Faraday’s law of electromagnetic induction .When the conductive liquid moves within the field ,voltage is inducted in it ,which is proportional in the velocity of the conductor. The equation is as below :
E=KBVD
K:Coefficient of the flow meter
B:Pulsed magnetic flux density
V:Average velocity of the media
D:Inner diameter of the measuring pipe
When measuring flow .fluid flow through the perpendicular of the flow field ,the liquid flow conductivity induction out a and average flow velocity(volume flow) proportional to the voltage signal ,the inductive voltage signal through the two and liquid direct contact with the electrodes of detection ,and through the cable ,and then sent to amplifer current signal conversion unity .
Characteristics and application scope
Chinese and English intelligent converter which displays all in Chinese adopts embedded 16-bit micro-controller.Full processing digitally,the converter has the functions of bidirectional way measurement ,forward & reverse accumulated and difference in values.It can be used to measure the volume of conductive liquids such as water ,sewage ,acid ,alkali and salt as well as mixture of liquid and solid.
