■Definition and terminology
Terminology
Definition
A Accumulated flow The total amount of fluid that has passed through the device. If an instantaneous
flow of 10 L/min continues for 5 minutes, the accumulated flow will be 5 x 10 = 50 L.
Accumulated flow external
reset A function to reset the accumulated flow to "0" when an external signal is input.
Accumulated pulse output A type of output where a pulse is generated every time a predefined accumulated flow passes. It is possible to calculate the total accumulated flow by counting the
pulses.
Accumulated value hold
A function to store the accumulated flow value in the internal memory. The flow
value will be stored at a set time interval of either 2 or 5 minutes. When the power
supply is turned on, the stored accumulated flow value will be displayed and
accumulated flow will continue from that point.
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.
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
Delay time
The setting time from when the flow applied to the flow switch reaches the set
value, to when the ON-OFF output actually begins working.
Delay time setting can prevent the output from chattering.
The response time indicates when the set value is 90% in relation to the step input.
Display flow range
The range which can be displayed by the product with a digital display.
Digital filter
Function to add digital filtering to the fluctuation of flow value. Smooth the
fluctuation of displayed value for sharp start up or fall of the flow.
When the function is valid, digital filtering is reflected to the ON/OFF of the switch
output.
Output chattering or flicker in the measurement mode display can be reduced by
setting the digital filter.
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] x 1% = 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 by the amount of
hysteresis or more.
I Instantaneous flow The volume of flow per unit of time. If it is 10 L/min, there is a flow of 10 Lpassing
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.

If the minimum setting unit is 1 L/min, the flow can be displayed in 1 L/min units, i.e.
10, 11, 12.
N Normal condition (NOR) Reference condition for volumetric flow: 101.3 kPa, 0 °C The flow measurement
which is converted at normal atmospheric pressure conditions at 0 °C.
O Operating fluid temperature The fluid temperature range within which the product will meet all published
specifications.
Operating humidity range The ambient humidity range within which the product will meet all published
specifications.
Operating pressure range
The pressure 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.
P
Part in contact with fluid
A part that comes into physical contact with the fluid.
Pressure characteristics The amount of variation in the analogue output or display value when the supply
pressure is changed.
Proof pressure
The pressure beyond which the product will be damaged.
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 flow is repeatedly
changing.
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 switch output turns ON (OFF) at 90% of
the rated flow rate.
Ripple
Indicates pulsation.
S Set flow range The range of ON/OFF threshold values that can be set for products with a switch
output.
Standard condition
(STD)
Reference condition for volumetric flow: 101.3 kPa, 20 °C, 65%RH The flow
measurement which is converted at normal atmospheric pressure conditions at
20 °C, 65%R.H.
Switch output An output type that has only 2 conditions, ON or OFF. In the ON condition an indicator LED will turn on, and any connected load will be powered. In the OFF
condition, there will be no indicator LED and no power is supplied to the load.
T Temperature characteristic The amount of variation in the analogue output or display value when the ambient
temperature is changed.
U Unit selection function Function to change the unit in which the value of flow is displayed. Only a product
with this function can change the unit. Aproduct with unit selection function cannot
be purchased if it is used within Japan. Flow is indicated only by SI units in Japan.
W Window comparator mode An operating mode in which the switch output is turned on or off depending on
whether the flow is within the range of 2 set values.
