●Product handling
Installation
Avoid displacement of the product and loose screws.
Tightening with excessive force may damage the product.
Ensure that the FG terminal is connected to ground when using a commercially available switch-mode
power supply.
Do not drop, hit or apply excessive shock to the product.
Otherwise damage to the internal parts can result, causing malfunction.
Do not pull the lead wire forcefully, or lift the product by the lead wire. (Tensile force 49 N or less)
Hold the product body when handling, to prevent damage, failure or malfunction.
The tensile strength of the power supply/output connection cable is 50 N and the sensor lead wire with a
connector is 25 N.
Any dust left in the piping should be flushed out by air blow before connecting the piping to the product.
Otherwise damage or malfunction can result.
Refer to the flow direction of the fluid indicated on the product label for installation and piping.
Do not mount the body with the bottom facing upwards.
Avoid piping in which the piping size of the IN side of the product changes suddenly.
If the piping size is reduced sharply or there is a restrictor such as a valve on the IN side, fluid velocity distribution
in the piping will be disturbed, leading to improper measurement.
Therefore, the above-mentioned piping should be connected on the OUT side.
If the OUT side is opened, or flow rate is excessive, cavitations may be generated, which may result in improper
measurement.
As a measure against this, it is possible to reduce the cavitations by increasing the fluid pressure.
Take action such as mounting an orifice on the OUT side of the product, and confirm that there is no malfunction
before handling.
If the orifice of the OUT side is fully closed to operate the pump, the switch may malfunction due to the effect of
pulsation (pressure fluctuation). Ensure that there is no malfunction before usage.
Do not insert metal wires or other foreign matter into the piping port.
This can damage the sensor causing failure or malfunction.
Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
If the fluid may contain foreign matter, install and connect a filter to the inlet.
The adherence of foreign matter to the vortex generator or detector can cause errors in measurement accuracy.
Design and install the application so that the fluid detection path is always full.
If the product is mounted vertically, let the liquid flow from bottom to top.
Trapped air bubbles can cause errors in measurement accuracy.
(If the fluid detection path is always filled with liquid, there will be no problem.)
If the PF2D5 and LQ fluoropolymer fittings series are ordered separately, it is not possible to assemble
them with the tubing insertion tool of the LQ series. Please send them back to SMC. After assembling it,
it will be delivered to you.

■Definition and terminology
Terms
Meaning
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
C
Cavitation
A phenomenon that may occur in a fluid moving at high speed. In the parts of the fluid
where the pressure is low, vapour bubbles form and then rapidly collapse. If cavitation
is present for a prolonged period, exposed surfaces will be damaged; this is called
cavitation damage or erosion.
F
Fluid temperature
Range of fluid temperature that can be measured by the product.
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.
K
Karman vortex
When an object is placed in a fluid stream, a vortex will be created in the fluid on the
downstream side. This vortex is called a Karman vortex. The frequency at which the
vortices are generated is proportional to the fluid velocity, therefore it is possible to
calculate the fluid flow rate by measuring the Karman vortex frequency.
O
Operating humidity
range
The ambient humidity 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 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.
T
Temperature
characteristics
The amount of variation in the analogue output or display value when the ambient
temperature is changed.
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.
