OFF
 The above are examples of integrated displays. (Same as remote monitor unit)
Line name display Fluid temperature display
Sub screen
Integrated display Remote monitor unit
Displays the set value. (The set value
of OUT2 cannot be displayed.)
Displays the accumulated value. (The
accumulated value of OUT2 cannot be
displayed.)
Displays the peak value.
Displays the line name. (Up to 6
alphanumeric characters can be input.)
Displays the fluid temperature.
(When the temperature sensor type is
selected.)
Displays nothing.
Displays the bottom value.
Series PF3W
Function Details 1
Set value display Accumulated value display Peak value display Bottom value display
! Selection of display on sub screen
The display on the sub screen in measuring mode can be set.
! Output operation
The output operation can be selected from the following:
Output (hysteresis mode and window comparator mode) corresponding
to instantaneous flow rate,
Output corresponding to accumulated flow,
Accumulated pulse output
Note) At the time of shipment from the factory, it is set to hysteresis
mode and normal output.
When a temperature sensor is attached, the output to the temperature
sensor is selectable only for OUT2.
(Refer to “How to Order” for details.)
ON: Green, OFF: Red
ON: Red, OFF: Green
Always: Red

! Indication color
The indication color can be selected for each
output condition. The selection of the indication
color provides visual identification of abnormal
values. (The indication color depends on OUT1
setting.)

! Response time
The response time can be selected depending on the application. (1
second for default setting)
Abnormalities can be detected more quickly by setting the response
time to 0.5 seconds.
The effect of the pump fluctuation and flickering of the display can be
reduced by setting the response time to 2 seconds.
Note) The temperature sensor output is fixed to 7 seconds.

! External input function
This function can be used when external input is available. The accumulated
value, peak value, and bottom value can be reset by remote control.
Accumulated flow external reset:
This function resets the accumulated value to “0” when an input signal
is applied.
In accumulated increment mode, the value will be zero when reset,
and the accumulated value will increase from zero.
In accumulated decrement mode, the value will be the set value when
reset, and the accumulated value will decrease from the set value.
 When the accumulated value is memorized, every time the accumulated
value external reset is activated, the memory element (EEPROM) will be
accessed. Take into consideration the maximum number of times the
memory element can be accessed, 1 million times. The total of external
input times and accumulated value memorizing time interval should not
exceed 1 million times.
Peak and bottom reset: Peak and bottom values are reset.
! Forced output function
Output is turned ON/OFF compulsorily when starting the system or
during maintenance. This enables confirmation of the wiring and
prevents system errors due to unexpected output.
For the analog output type, the output will be 5 V or 20 mA for ON and
1 V or 4 mA for OFF.
 Also, the increase or decrease of the flow and temperature will not
change the on/off status of the output while the forced output
function is activated.
! Accumulated value hold function
Accumulated value can be saved on the unit even when the power
supply is turned off.
The accumulated value is memorized every 2 or 5 minutes during
measurement, and continues from the last memorized value when
the power supply is turned on again.
The lifetime of the memory element is 1 million access cycles. Take
this into consideration before using this function.
! Peak/Bottom value indication
The maximum (minimum) flow is detected and updated from when
the power supply is turned on. In peak (bottom) value indication
mode, this maximum (minimum) flow is displayed.
! Setting of secret code
Users can select whether a secret code must be entered to release
key lock. At the time of shipment from the factory, it is set such that
the secret code is not required.
! Power saving mode
The display can be turned off to reduce the power consumption.
In power saving mode, decimal points blink on the main screen.
If any button is pressed during power saving mode, the display is
recovered for 30 seconds to check the flow, etc.
! Keylock function
Prevents operation errors such as accidentally changing setting
values.
