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.

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, GPRS output
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
