■ STANDARD SPECIFICATIONS
Note •For models with no setting switches, a hand-
held terminal is necessary to set parameters.
•Pulse output, status output and alarm output
use commom terminals, therefore, these
functions are not available at the same time.
Excitation method: Pulsed DC excitation
Output Signal:
Current Output: 4 to 20 mA DC
(Load resistance 600
Ω
maximum)
Transistor Contact Output(Open-collector):
Pulse, alarm or status output selected by
parameter setting (Contact rating : 30V
DC(OFF), 200mA*(ON))
* In case of FM-Nonincendive type, 135mA
Communication:
HART or BRAIN
(Superimposed on the 4 to 20mA DC signal)
Conditions of Communication Line:
Load Resistance: (including cable resistance)
HART: 230 to 600
Ω
, depending on q’ty of field
devices connected to the loop (multidrop
mode)
BRAIN:250 to 600

F maximum
Load Inductance: 3.3 mH maximum
Distance from Power Line: 15 cm(0.6 ft) or more
(Parallel wiring should be avoided.)
Input Impedance of Receiver Connected to the
Receiving Resistance: 10k
Ω
or larger (at 2.4kHz)
(only for HART)
Maximum Cable Length: 2 km* (6500 ft) (when
polyethylene-insulated PVC-sheathed
control cables (CEV cables) are used)
* In case of FM-Nonincendive type, 1.5km(4875ft)
Instantaneous Flow Rate Display Function:
Flow rate can be displayed either in engineering
units or in percent of span. (for models with
indicator)
Totalizer Display Function:
Totalized volume in engineering units can be
displayed by setting a totalizing factor. (for
models with indicator)
Span Setting Function:
Volumetric flow setting is available by setting
volume unit, time unit, flow rate value and flow
tube size.
Volume Unit: m
3 , l, cm 3 , gallon(US),
barrel(=158.987L)
Velocity Unit: m, ft
Time Unit: sec., min., hour, day
Flow Tube Size: mm, inch
Data Security During Power Failure:
Data storage in EEPROM - no back-up battery
required.
Damping Time Constant:
Settable from 0.5 second to 200 seconds. (63%
response time)
Pulse Output Function:
Scaled pulse can be output by setting a pulse
factor.
Pulse Width: Duty 50% or fixed pulse width (0.5,
1, 20, 33, 50, or 100ms) - user selectable.
Output Rate: 0.0001 to 1000pps (when pulse
output function is selected.)
Status Output Function:
One of the followings is selected by parameter
setting.
• Auto 2 Ranges Status Output :
Indicates the selected range for automatic
dual range function.
• Forward and Reverse Status Output :
Indicates the flow direction for forward and
reverse flow measurement mode.
• Totalization Status Output :
Indicates that the internal totalized value ex-
ceeds the set value.
• Low Limit Alarm :
Indicates that flow rate under the low limit set
value.
Alarm Output Function :
Indicates that an alarm occurs (Normal Close
Fixed).
Self Diagnostics Function:
Converter failure, flow tube failure, erroneous
setting, etc. can be diagnosed and displayed (for
models with indicator).
Touch Control:
Parameter setting operation by infrared switches.
(for models with indicator and setting switches)
Electrical Connection:
ANSI 1/2NPT female, DIN Pg13.5 female,
ISO M20 X 1.5 female, JIS G1/2 female
Terminal Connection: M4 size screw terminal

Mounting: 2-inch pipe mounting
Grounding: 100
Ω
or less
*In case of explosion proof type, the protective grounding
must be connected to a suitable IS grounding system.
