■Definition and terminology
Term
Definition
A
Analogue output
An Output value proportional to the flow rate. When the analogue output is in
the range of 1 to 5 V, it will vary between 1 to 5 V according to the flow rate
change. The same occurs for analogue output of 0 to 10 V and 4 to 20 mA.
Auto-shift
Function where the switch output state is determined by the change in
instantaneous flow rate, relative to a reference value set when an external
input signal is received.
Auto-shift zero
The same as auto-shift, but in addition the display is set to zero when the
external input signal is received, and therefore the display indicates the change
of instantaneous flow from the reference value.
Auto-preset
This function calculates and sets the flow values automatically based on the
ongoing operation.
B
Bottom value display (mode)
The minimum flow recorded from when the power was supplied to the present time.
C
Chattering
The problem of the switch output turning ON and OFF repeatedly around the set
value at high frequency due to the effect of pulsation.
Copy function
Function to copy the set values of the copy source to a copy destination.
D
Delay time
The setting time from when the connected flow sensor signal reaches the set
value, to when the ON-OFF output actually operates.Adjusting the delay time
can prevent the output from chattering.
Digit
(smallest settable increment)
How precisely the pressure can be displayed or set. When 1 digit = 1 L/min, the
value is displayed in increments of 1 L/min, e.g., 1, 2, 3, …, 99, 100.
Digital filter
Function to add digital filtering to any fluctuation in the input signal.
Smooth the fluctuation of the displayed value for sharp start up or fall of the flow.
When the function is used, digital filtering is reflected in the switch output
ON/OFF or analogue output. Output chattering or display flicker in
measurement mode can be reduced by setting the digital filter.
The response time indicates when the set value is 90% in relation to the step input.
Display accuracy
The maximum deviation between the displayed flow rate and the actual flow rate.
Display colour
Indicates the colour of the digital display.
Always green, always red, green (switch OFF) changing to red (switch ON), or
red (switch OFF) changing to green (switch ON) are available in window
comparator mode.
Display flow (voltage) range
The range of flow that can be displayed.
Display resolution
Indicates into how many units the rated flow range can be divided.
(Example: When the value can be displayed down to 0.01 L/min for a product
with a rated flow range of 1.0 L/min, the resolution is 1/100).
E
Energy saving mode
Operating mode in which the digital display turns off to reduce power consumption.
Error display
A code number displayed to identify the error code detected by the
self-diagnostic function of the product.
Refer to "Error indication function" on page 73 for details of the errors.
Error output
Switches the switch output to ON/OFF when an error is displayed.
F
F.S.
(full span/full scale)
This means "full span" or "full scale", and indicates a varied analogue output
range at a rated value.
For example, when the analogue output is 1 to 5 V, F.S. = 5 [V] - 1 [V] = 4 [V].
(Reference: 1%F.S. = 4 [V] x 1% = 0.04 [V])
Function selection mode
The mode in which setting of functions is performed. It is a separate menu from
the display setting. If any function settings need to be changed from the factory
default, each setting can be selected with "F". The setting items are: display
colour, display range, display units, operation mode, output type, delay time,
digital filter, power saving mode, security code, etc.

Term
Definition
H
Hysteresis
The difference between ON and OFF points used to prevent chattering.
Hysteresis can be effective in avoiding the effects of pulsation.
Hysteresis mode
Mode where the switch output will turn ON when the flow is greater than the set
value, and will turn OFF when the flow falls below the set value by the amount of
hysteresis or more.
I
Insulation resistance
The insulation resistance between the electrical circuit and the case.
K
Key-lock function
Function that prevents changes to the settings (disables button operation).
M
Maximum applied voltage
The maximum voltage that can be connected to the output of an NPN device.
Maximum load current
The maximum current that can flow to the switch output.
Measurement mode
Operating condition in which pressure is being detected and displayed, and the
switch function is working.
Minimum resolution
Refer to "digit".
N
Normal output
One of the switch output types. In hysteresis mode the switch output is turned
ON when flow equal to or greater than the switch output set value is detected. In
window comparator mode, the switch output is turned ON when flow between
the switch output set values (P1L to P1H) is detected.
O
Operation LED
An LED that turns on when the switch output is ON.
Operation mode
Operation selected from Hysteresis mode/ Window comparator mode/
Accumulated output mode/Accumulated pulse mode/ Error detection mode/
Output OFF mode.
Output
The operation principle of the switch output. Normal output and reverse output
can be selected.
P
Peak value display (mode)
The maximum flow rate recorded from when the power was supplied to the
present time.
R
Rated flow (voltage) range
The flow range within which the product will meet all published specifications.
Repeatability
The repeatability of the display or analogue output value, when the measured
flow quantity is repeatedly increased and decreased.
Resolution
Refer to "Display resolution".
Reversed output
One of the switch output types. In hysteresis mode the switch output is turned
ON when a flow less than or equal to the switch output set value is detected. In
window comparator mode, the switch output is turned ON when flow outside of
the switch output set values (n1L to n1H) is detected.
Ripple
A type of chattering.
S
Set point range
The flow range that can be set for the switch output.
Switch output
Output type that only has 2 possible states, ON or OFF. Sometimes referred to
as "ON-OFF output".
U
Units selection function
A function to select the display units other than the international units (SI units)
specified in Japanese measurement law. The product for use in Japan is not
equipped with this function.
W
Window comparator mode
An operating mode in which the switch output is turned on and off depending on
whether the flow is inside or outside a range of two set values.
Withstand voltage
A measure of the product’s resistance to a voltage applied between the
electrical circuit and case. The product may be damaged if a voltage above this
value is applied.
(The withstand voltage is not the supply voltage used to power the product).
