AM**0/**0 Electromagnetic Flow meter(CE Approved) is the advanced
engineering designed magnetic flowmeter, It has a dual cavity
housing providing ease of wiring while isolating the electronics
from the environment. AM**0/**0 continues the use of low frequency
excitation, which provides noise free output. AM**0/**0 excitation
method and multiform lining allow this magnetic flowmeter to be
applied to an even greater range of applications

Measuring Range
The velocity range is 0.3m/s to *5m/s. The minimum measurable speed
can be one percent (1%) of the full range.

Analog Output
Current output: fully-isolated 0 - *0mA / 4 - *0mA
Load resistance: 0 to 1.5kΩ at 0 - *0mA; 0 to **0Ω at 4 - *0mA
Base error: add ±*0μA 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 ***0 Hz. The external DC power
supply should not exceed *5V and maximum collector current is
**0mA.
Pulse Output
The converter can output up to ***0cp/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 ********9p/L,
********9p/m3, ***1~***9p/kg or ***1~***9p/t. Pulse width is
selectable from *6ms, *3 ms, *6mm, *9ms or auto square wave.
Photo-coupler isolated transistor open collector circuit is used
for pulse output. The external DC power supply should not exceed
*5V and maximum collector current is **0mA.
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 **2V 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 *5V and maximum collector current is **0mA.
Communication
The RS**5, RS**2C, 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 **0s
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
