■Definition and terminology
Terminology
Definition
A
Analogue output
A type of variable output that has a value proportional to the
measured quantity. When the analogue output is in the range of 1 to
5 V or 4 to 20 mA, it will vary continuously, following the change of
flow.
Auto-preset
This function calculates and sets an approximate set value
automatically based on the on-going operation.
Auto-shift
A function where the switch output state is determined by the change
in instantaneous flow rate, relative to a reference value set when an
external signal is input.
Auto-shift zero
As the auto-shift function, but in addition the display is also set to
zero when the external signal is input, and so the display shows the
change of instantaneous flow from the reference value.
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.
D
Display voltage (flow) range
The range that which can be displayed by the product with a digital
display.
F
F.S. (Full span, Full scale)
Stands for "full span" or "full scale", and indicates varied analogue
output range at rated value. For example, when analogue output is 1
to 5 V, F.S. = 5[V] - 1[V] = 4[V], (ref. 1%F.S. = 4[V]x1% = 0.04[V])
The maximum measuring range or change in analogue output over
the maximum measurement range.
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 – hysteresis value.
I
Instantaneous flow
The flow passing per unit of time. If it is 10 L/min, there is a flow of 10
L passing through the device in 1 minute.
Internal voltage drop
The voltage drop across the product (and therefore not applied to the
load), when the switch output is ON. The voltage drop will vary with
load current, and ideally should be 0 V.
K
Key-lock function
A function that locks the set buttons so that no accidental setting
changes can be made.
M
Minimum. setting unit
The resolution of set and display values.
If the minimum setting unit is 1 L/min, the flow can be displayed in
1 L/min units, i.e. 10, 11, 12.
O
Operating hamidity range
The ambient hamidity range within which the product will meet all
published specifications.
Operating temperature range
The ambient temperature range within which the product will meet all
published specifications.

Terminology
Definition
P
Power saving mode
The condition in which the digital display turns off and current
consumption is reduced.
R
Rated flow range
The flow range within which the product will meet all published
specifications.
Repeatability
Reproducibility of the display or analogue output value, when the
measured quantity is repeatedly increased and decreased
Response time (Analogue output)
The time from when the flow is applied as a step input (when the flow
rate changes from 0% to 100% instantaneously) until the analogue
output (voltage or current) reaches 90% of the actual flow rate.
Response time (Switch output)
The time from when the flow is applied as a step input (when the flow
rate changes from 0% to 100% instantaneously) until the switch
output turns ON (OFF) at 90% of the rated flow rate.
S
Set voltage (flow) range
The range of ON/OFF threshold values that can be set for those
products with a switch output.
Switch output
Output type that has only 2 conditions, ON or OFF. When in the ON
condition an indicator light will show, and any connected load will be
powered. When in the OFF condition, there will be no indicator light
and no power is supplied to the load.
T
Temperature characteristic
The amount of variation in the analogue output or display value when
ambient temperature is changed.
U
Unit selection function
A function to select display units other than the international unit (SI
unit) specified in the new Japanese measurement law. Flow can only
be displayed using SI units in Japan.
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 the range of two
set values.

Mounting and Installation
■Installation
Panel mounting
Fix the panel mount adapter to the monitor with the mounting screws (M3x8 L) supplied.
The monitor can be mounted on a panel with a thickness of 0.5 to 6.0 mm.
Refer to the dimension drawing (page 54) for panel cut-out dimensions.
Note when removing the monitor
The flow monitor with panel mount adapter can be removed from the installation by removing 2 screws and
releasing the hooks at the sides, as illustrated.
Take care not to damage the product and panel mount adapter.

No.PF※※-OMN0005-E
Bracket mounting
Mount the bracket using the mounting screws (M3 x 5 L) supplied.
The required tightening torque is 0.5 to 0.7 Nm.
Install the product (with bracket) using the M4 screws (2 pcs.).
Bracket thickness is approximately 1.6 mm.
Refer to the dimension drawing of the bracket (page 55) for mounting hole dimensions.

No.PF※※-OMN0005-E
■Wiring
Wiring of connector
Connections should only be made with the power supply turned off.
Use separate routes for the product wiring and any power or high voltage wiring. Otherwise, malfunction
may result due to noise.
Ensure that the FG terminal is connected to ground when using a commercially available switch-mode
power supply. When a switch-mode power supply is connected to the product, switching noise will be
superimposed and the product specification can no longer be met. This can be prevented by inserting a
noise filter, such as a line noise filter and ferrite core, between the switch-mode power supply and the
product, or by using a series power supply instead of a switch-mode power supply.
Attaching the connector to the sensor wire
Strip the sensor wire as shown.
Do not cut the insulator.
Insert the corresponding wire colour shown in the table into
the pin number printed on the sensor connector, to the
bottom.
Pin no.

Check that the above preparation has been performed correctly, then part A shown should be pressed in
by hand to make temporary connection.
Part A should then be pressed in using a suitable tool, such as pliers.
The sensor connector cannot be re-used once it has been fully crimped.
In cases of connection failure such as incorrect order of wires or incomplete insertion, please use a new
connector.
If the sensor is not connected correctly “LLL” or “HHH” will be displayed.
