Function Details
Display colour
The display colour can be selected for each
output condition. The selection of the dis-
play colour provides visual identifi cation of
abnormal values.
Simple setting mode
Only the set values for instantaneous fl ow and accumulated fl ow can
be changed. Output mode, output type, display colour, and
accumulate pulse output cannot be changed.
Output operation
The output operation can be selected from the following:
Output (hysteresis mode and window comparator mode) correspond-
ing to instantaneous fl ow or output (accumulated output and pulse
output) corresponding to accumulated fl ow.
(Default setting: Hysteresis mode, Normal output)
External input function
The accumulated fl ow, peak value, and bottom value can be reset remotely.
Accumulated value external reset: A function to reset the accumulated fl ow value when an
external input signal is applied.
In accumulated increment mode, the accumulated
value will reset to and increase from zero.
In accumulated decrement mode, the accumulated
value will reset to and decrease from the set value.
∗
When the accumulated value is stored to memory, every time the accumulated
value external reset is activated, the memory will be accessed. Take into
consideration that the maximum number of times the memory can be accessed
is 1.5 million times. The total number of external inputs and the accumulated
value memorizing time interval should not exceed 1.5 million times.
Peak/Bottom value reset: Peak and bottom value are reset.
Forced output function
The output is turned on/off in a fi xed state when starting the system
or during maintenance. This enables the confi rmation of wiring and
prevents system errors due to unexpected output.
For the analogue output type: When ON, the output will be 5 V (or 10
V when 0 to 10 V is selected) or 20 mA, and when OFF, 1 V (or 0 V
when 0 to 10 V is selected) or 4 mA.
∗
Also, an increase or decrease of the fl ow will not change the on/off
status of the output while the forced output function is activated.
Accumulated value hold
The accumulated value is not cleared 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 maximum writable limit of the memory device is 1.5 million times,
which should be taken into consideration.
Peak/Bottom value display
The maximum (minimum) fl ow rate is detected and updated from
when the power supply is turned on. In peak (bottom) value display
mode, this maximum (minimum) fl ow rate is displayed.
Setting of security code
The user can select whether a security code must be entered to re-
lease the key lock. At the time of shipment from the factory, it is set
such that a security code is not required.
Key-lock function
Prevents operation errors such as accidentally changing setting values
Display with zero cut-off setting
When the fl ow is close to 0 l/min, the product will round the value
down and zero will be displayed. A fl ow value may be displayed even
when the fl ow rate is 0 l/min due to high pressure or depending on the
installation. The zero-cut function will force the display to zero. The
range to display zero can be changed.
FUNC output switching function
Analogue output, external input, or copy function can be selected.
(Default setting: Analogue output)
Selectable analogue output function
1 to 5 V or 0 to 10 V can be selected for the analogue voltage output
type. (Default setting: 1 to 5 V)
Reset to the default settings
The product can be returned to its factory default settings.
Delay time setting
The time from when the instantaneous fl ow
reaches the set value to when the switch
output operates can be set. Setting the
delay time can prevent the switch output
from chattering.
(Default setting: 0 s)
Digital fi lter setting
The time for the digital fi lter can be set to the
sensor input. Setting the digital fi lter can
reduce chattering of the switch output and
fl ickering of the analogue output and the
display.
The response time indicates when the set
value is 90 % in relation to the step input.
(Default setting: 0 s)
