Meaning
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 flow switch will be damaged.
R
Rated flow range
The flow range within which the product will meet all published specifications.
Rated pressure range
The pressure 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
Time from when the target flow is applied until the flow reaches 90% of the Set value.
S
Setting flow range
The range of ON/OFF threshold values that can be set for flow switches products with a
switch output.
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
characteristics
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. A product with unit selection function cannot be
purchased if it is used within Japan. Flow is indicated only by SI units in Japan.
W
Water hammer
A momentary steep pressure increase due the spread of pressure by closing a
contactor such as a valve for an extremely short time while there is a flow.
This pressure increase is known as water hammer or impact pressure.
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.
