Basic Info.
Product Description
Electromagnetic Flowmeter is composed of sensor and converter, works on Faraday"s electromagnetic indiction principle, it has a dual cavity housing providing ease of wiring while isolating the electronics from the environment. ETFM continues the use of low frequency excitation method and multiform lining allow this magnetic flowmeter to be applied to an even greater range of applications.
FEATURES
Fast response and high stability.
High Accuracy, , 0.2% for flowrate
Dual cavity housing to separate electronics part from wiring part.
AC power supply common use (85~265vac).
High visible backlit LCD for easy operation.
Communication: E. G. RS485, RS232C, HART, Profibus, MODBUS etc.
BI-direction measuring and totalizing
STANDARD SPECIFICATIONS
Coverter
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.
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
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.
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. Photo-coupler 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.
Showing Flow Directione
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. Alarm Output
Two channel of phpto-coupler 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.
Communication:
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 signal can be used to remotely control the start/stop or reset of internal counter.
Display Function:
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.
Self Diagnostics Function:
Converter failure, flow tube ffailure, erroneous setting, etc. Can be diagnosed and displayed.
Data Security During power Failure:
Data storage by EEPROM-no back-up battery required.
