If the "Sensor type" is CB or CS, then "Temp (Outer)" will be added, and "Volume ow" will not be shown.
3.5 Menu: Process Variables (Processing Values Display)
The "Process Variables" menu can be used to conrm the owmeter’s process values (instantaneous ow
value, uid density, uid temperature, cumulative total ow value, and analog output), as well as the Write
Protect state.
For the actual screen, refer to Fig. 16.

3.6 Menu: Setup (Settings)
The "Setup" menu can be used to set the flowmeter’s various parameter values, the converter’s
information, and so on.
If a "Diag/Service" window is displayed on the screen, then it will not be possible to set the various
parameters, converter information, and so on. Close these window before making settings.
For the actual screen, refer to Fig. 19.

3.6.1 Converter variables (Fld dev var)
①Click "Setup (S)" in the menu, and then select and click "Fld dev var".
②The following window will be displayed (Fig. 20).
Fig.20
③In the "Flow" section, the mass ow unit, volume ow unit, inow direction, ow damping, ow cutoff,
and volume ow compensation coefcient can be set.
If the "Sensor type" is CB or CS, then the volume ow unit "Vol ow unit" and "Vol ow coef" selection
items will not be displayed.
The ow direction can be set to either "Forward" or "Reverse", whereby "Forward" means the direction
indicated for the ow direction on the owmeter unit is treated as the "positive direction", and "Reverse"
means the opposite direction from the arrow is treated as the "positive direction". Flow cutoff indicates
a percentage of the maximum allowed ow, with the standard setting at "0.3%". This functions both in
the positive and negative directions.
④In the "Density" section, the density unit, density damping, gas multiphase ow determination, density
compensation, and settled density can be set.
If the gas multiphase ow determination exceeds the setting value of the measurement density’s
"Slug low limit" or "Slug high limit", then this is seen as a gas multiphase ow, and the owmeter
side’s result and output are forcibly set to "0". When "Slug low limit" is set to "0" and "Slug high limit" is
set to "10", the gas multiphase ow determination function is turned "OFF". Also, if it is within the time
set in "Slug duration", then the gas multiphase ow state will be ignored, and ordinary measurements
will be continued.
When density compensation "Compensation" is set to "ON", the density and volume flow become
values that are converted based on the base temperature (calculated with "Standard temp" and
"Expansion coef").
When settled density "Settled dens" is set to "ON", then the value set with "Dens value" is reected in
the volume ow.

E-023-2-E

⑤In the temperature "Temp" section, the temperature unit and temperature damping can be set.
⑥Set each item. For the items with a triangle on the right side, click the triangle to make your selection
from the drop-down list. For the other items, directly input a numerical value.
⑦After all settings are complete, click the "OK" button to display a message box (Fig. 21).
Click "OK" here to change the settings to the inputted values, and to reect the changed setting values
in the owmeter’s output. For the sake of safety, if the owmeter’s output is used to control valves or
other such parts, then change that control loop to manual control so that the control loop is in a state
whereby it is not inuenced by the owmeter’s output.
⑧Click "OK" to change the settings to the inputted values, and then click the "OK" button in the displayed
message box (Fig. 22) to complete the setting process.
⑨After the "OK" button is clicked, the item input window will appear again. Click the "Cancel" button to
close the item input window.
To cancel the settings, click the "Cancel" button in any step from ②to ⑦.
CAUTION
If the unit is changed, then it will be necessary to update the units included in
other windows.
If a window including units is opened, then close that window and reopen it to
update the units.

3.6.2 Output settings (Outputs)
3.6.2.1 Analog and pulse assignment (Analog/Pulse Assign)
①Click the "Setup (S)" menu, and then select and click "Analog/Pulse Assign" from the "Outputs" drop-
down list.
②The following window will be displayed (Fig. 23). Assign analog output 1 and 2 here, as well as pulse
output 1 and 2.
③Set each item assignment. Make your selections from the drop-down lists by clicking the triangles on
the right side of each item, as shown in Fig. 24, Fig. 25, and Fig. 26.
If the "Sensor type" is CB or CS, then the "Pulse output 1" and "Pulse output 2" selection items will be
xed at "Mass ow", and therefore will not be displayed.
Also, when the "Pulse output 2" selection items "Double Pulse 90", "Double Pulse -90", and "Double
Pulse 180" are selected, the setting becomes the phase difference with "Pulse 1".

④Click the "OK" button after all settings are completed to display the message box (Fig. 27).
Click "OK" here to change the settings to the inputted values, and to reect the changed setting values
in the owmeter’s output. For the sake of safety, if the owmeter’s output is used to control valves or
other such parts, then change that control loop to manual control so that the control loop is in a state
whereby it is not inuenced by the owmeter’s output.
When the pulse output assignment is modied, the cumulative total will be reset, and a conrmation
message box will be displayed as shown in Fig. 28. To avoid resetting the cumulative total, click the
"Cancel" button. If you do not mind resetting the total, click the "OK" button again.
Also note that if "Cancel" is clicked, settings will not be modied.
⑤Click "OK" to change the settings to the inputted values, and then click the "OK" button in the displayed
message box (Fig. 29) to complete the setting process.
Also note that when the analog output assignment is changed, this can generate an alarm.
In this case, the message box shown in Fig. 30 will be displayed.

⑥After the "OK" button is clicked, the item input window will appear again. Click the "Cancel" button to
close the item input window.
To cancel the settings, click the "Cancel" button in any step from ②to ④.
3.6.2.2 Analog output 1 setting (Analog output 1)
①Click the "Setup (S)" menu, and then select and click "Analog output 1" from the "Outputs" drop-down
list.
②The following window will be displayed (Fig. 31). Set analog output 1 here.
③Set each item. USL (the sensor’s upper limit) and LSL (the sensor’s lower limit) indicate the input
range of URV (20mA setting) and LRV (4mA setting), so use this as a rule of thumb when making your
settings.
When "Lowcut" is set to "0.0%", the lowcut function is turned off. "0.0%" is the standard setting. If
anything other than ow (mass or volume) is assigned, be sure to set 0.0%. Also note that when "Bi
direction" is selected, the lowcut function will work in both positive and negative directions.
④Click the "OK" button after all settings are completed to display the message box (Fig. 32).
Click "OK" here to change the settings to the inputted values, and to reect the changed setting values
in the owmeter’s output. For the sake of safety, if the owmeter’s output is used to control valves or
other such parts, then change that control loop to manual control so that the control loop is in a state
whereby it is not inuenced by the owmeter’s output.
