AM200/300 is the advanced engineering designed magnetic
flowmeter, It has a dual cavity housing providing ease of
wiring while isolating the electronics from the environment.
AM200/300 continues the use of low frequency excitation,
which provides noise free output. AM200/300 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, 0.5% of flow rate.
Dual cavity housing to separate electronics part from
wiring part.
AC power supply common use (80/264V).
High visible backlit LCD for easy operation.
With multiform communication e.g. RS485、RS232C、
HART、Pfofibus、MODBUS etc.
Bi-direction measuring and totalizing
STANDARD SPECIFICATIONS:
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 resistance: 0 to 1.5kΩ at 0 - 10mA; 0 to 750Ω at
4 - 20mA
Base error: add ±10μA 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 5000 Hz. 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 count per unit volume or mass. It can be set to 0001-9999p/L, 0001-9999p/m3, 0001～9999p/kg or 0001～9999p/t. Pulse width is selectable from 16ms, 33 ms, 66mm, 99ms or auto square wave. Photo-coupler isolated transistor open collector circuit is used for pulse output. The external DC power supply should not exceed 35V and maximum collector current is 250mA.
Showing Flow Direction & Range:
The converter is capable of measuring both forward and reverse flow and recognizing its direction. The converter outputs 0V low level for forward flow, while +12V high level for reverse flow.
Alarm Out：
Two channels of photo-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 250mA.
Communication:
The RS485, RS232C, HART, Profibus, MODBUS communication interface are embedded in the converter. Surge absorber is optional to protect the interface and converter.
Damping Constant:
Damping time is optional from 0.2 to 100s.
Input Contact
External contact ON (close) or OFF (open) signal can be used to remotely control the start/stop or reset of internal counter.
Display Function:
Flow rate can be displayed either in engineering units or in percent of span. Totalized volume in any engineering unit can be displayed by setting a totalizing factor
Self Diagnostics Function:
Converter failure, flow tube failure, erroneous setting, etc. can be diagnosed and displayed.
Data Security During Power Failure:
Data storage by EEPROM - no back-up battery required.
