The electromagnetic flowmeter (magnetic flowmeter) are excellent product with outstanding reliability and ease of operation,developed on the basis of decades of field-proven experience.
Electromagnetic flowmeters are suitable for measuring the flow of almost all electrically conducting liquids,pastes and slurries. A prerequisite is that the medium must have a minimum conductivity of 5 uS/cm. The temperature,pressure ,density and viscosity have no infulence on the result .
The main applications of the electromagnetic flowmeters can be found in the following sectors:
Water and waste water
Chemical and pharmaceutical industries
Food and beverage industry
Mining,aggregates and cements industries
Pulp and paper industry
Power,utlity and chilled water industry
The wide variety of combinations and versions from the modular system means that the ideal adaptation is possible to each measuring task . -
l Fast response and high stability.
l High Accuracy, 0.5%, 0.2% for flowrate
l Dual cavity housing to separate electronics part from wiring part.
l AC power supply common use (85~265vac).
l High visible backlit LCD for easy operation.
l Communication: e.g. RS485, RS232C, HART, Profibus,MODBUS etc.
l BI-direction measuring and totalizing
l Measuring Range
The velocity range is 0.3m/s to 15m/s. The minimum measurable speed can be one percent(1%) of the full range.
l Analog Output
Current output: fully-isolated 0~10mA/4~20mA
Load resitance: o to 1.5k; 4~20mA, 0~750 at 4~20mA
Base error: add minus 10uA on top of the measurement error
l Frequency Output
Frequency output is proportional to the flow percentage of the full range. It Provides fully isolated transistor open collector frequency output
ranged from 1 to 5000hz, the external Dc power supply should not exceed 35V and maximum collector current is 250mA.
l Pulse output
The converter can output up to 5000cp/s pulse series, which is dedicated to external totalization. Pulse factor is defined as pulse width is
selectable from 16ms, 33ms, 66mm, and so on.
P Hotocoupler isolated transistor open collectr circuit is used for pulse output. The external Dc power supply should not exceed 35V and
maximum collector current is 250mA.
l Showing Flow Direction&Range
The converter is capable of measuring both forward and reverse flow and recognizing its direction.The converter output 0Vlow level for
forward flow,while+12V high level for reverse flow.
Two channel of phptocoupler isolated open collector circuit are used for alarm signal output.There are two alarm outputs :high limit alarm
and low limit alarm.The external DC power supply should not exceed 35V and maximum collector current is 25OmA.
RS232C, RS485,HART,PROFIBUS ,MODBUS
The RS232C, RS485,HART,PROFIBUS ,MODBUS Communication interface are embedded in the converter.Surge absorber is optional to protect the interface and converter.
▲Damping Constant:Damping time optional from 0.2 to 100s.
▲Input Contact:External contact ON or OFF singal can be used to remotely control the start/stop or reset of internal counter.
Flowrate can be displayed either in engineering units or in percent of span.Totalized volum in any engineering unit can be displayed by setting a totalizing factor.
