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.
Accuracy:
DN (mm) | Velocity (m/s) | Accuracy |
| 25 ~400 | 0.1～0.3 | ±0.25%FS |
| 0.3～1 | ±0.5%FS |
| 1～15 | ±0.5%FS |
| % FS: Relative range;% R: Measurement. |
Analog Output:Current output: fully-isolated 0 - 10mA / 4 - 20mA Load resistance:
0 to 1.5k at 0 - 10mA; 0 to 750 at 4 - 20mA Base error: add ±10A 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 ContactExternal 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.
