       AFTLD 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 densityviscositytemperature 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 reading 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 pulsedigital communicationHART.

The converter has alarm output function of self-diagnosis empty load test high and low limit of the flow two-stage flow valuebatch 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.



Technical parameters 


 
Main power AC220V 50HZ / DC24V  
Power consumption <15W (And set with sensor supporting power consumption )
Display and push buttons The big screen LCD display with back lighting can display the instantaneous flow ,total flow and percentage of flow as well as alarm display ,four thin-film touch nubs ,which is used to data set .
Accumulator Forward total quantity ,reverse total quantity
Output signal Analog output Bi-direction with two ways ,Isolation 0-10mA/4-20mA
Load resistor:0-10Ma;0-1.5KΩ;4-20Ma;0-750Ω
Frequency output Forward & reverse flow output with frequency range set between 1-5000Hz.The external voltage must be lower than 35V and the max output and the max output current is 50Ma when the transistor is turned on
Alarm output Two outputs from the collectors of photoelectric isolate transistors are for alarm signals .The external voltage must be lower than 35V and the max output current is 250Ma when the transistor is turned on.Alarm status:Activates when the measured pipes are empty ,the excitation circuits are broken or the volume of flow rate exceeds the value designed limits.
Pulse output For pulse output in forward and reverse flow measurement ,upper frequency of pulse output can be up to 5000 CP/S relevant value of pulse is from 0.0001 to 1.0 M3/P .The width of pulse can be set to 20ms or squired wave from automatically.The collector of transistor with photoelectric is open circuited.The external voltage must be lower than 35 V and maximum output current is 250Ma when the transistor is turned on .
Accuracy ±0.5% of the value displayed ,±0.3% or ±0.2% are selectable.
Damping time constant Continuous variable from 0-100 s (90%)can be selected by group
Communication RS232 ,RS485 or HART Communication are selectable ,with lighting resistance
Power failure An anti-failure clock is designed in the flow meter which can save the power failure records for 16 times (10 years)
Protection class IP65
Ex-proof Mark Exd[ia]ia‖Ct5
