Handling Instructions and Precautions
Safety Precautions
●
Do not subject the flow meter cables to excess load by pulling on them, by
picking up the flow meter by them, or by placing heavy objects on them.
Such actions could result in current leaks or defective continuity that lead to
fire, electric shocks, or abnormal operation.
●
While handling the flow meter, do not subject it to excessive shock (490 m/s
2
or greater) by hitting, dropping or bumping it. Even if the product appears
undamaged, damage to internal components can cause abnormal operation.
●
Avoid load short-circuit conditions.
Turning on switch output while a load short-circuit condition exists can cause
damage to the flow meter due to over current.
Load short-circuit example: Connecting output lead wires of switch output to
DC power supply.
ATTENTION
●
Whenever considering use of this product in situations or environments not
specifically noted in the catalog or instruction manual, or in applications where
safety is an important requirement such as in aviation facilities, combustion
equipment, leisure equipment, safety equipment, and other places where
human life or assets may be greatly affected, take adequate safety
precautions such as allowing plenty of margin for ratings and performance, or
fail-safe measures. Be sure to consult us with such applications.
●
Always check the catalog and other reference materials for product wiring
and piping.
●
Do not configure control of the system in a way that could cause workpieces
to fall due to power failure.
Configure control of the system to prevent workpieces and other items from
falling due to power failure or by emergency stops of mechanical devices.
●
When handling the product, wear protective gloves, safety glasses, safety
shoes, and other protective clothing.
●
When the product can no longer be used or is no longer necessary, dispose
of it appropriately as industrial waste.
●
Pneumatic equipment can exhibit degraded performance and function over
its operating life. Always conduct daily inspections of the pneumatic
equipment, and confirm that all requisite system functions are satisfied, to
prevent accidents from happening.

General Precautions
Mounting location
Avoid installing the FA Series Flow Meter in the following types of locations.
1. Locations where the ambient temperature or product temperature is −10℃
or below or exceeds 60℃.
2. Locations where the ambient humidity exceeds 90% RH.
3.
Locations subjected to sudden temperature changes that can cause condensation.
4. Locations subjected to concentrations of corrosive and/or flammable gasses.
5.
Locations subjected to high amounts of dust, salt, iron powder, or other
conductive matter, moisture, oil mist, or organic solvents.
6.
Locations where the product is directly subjected to vibration and/or impact.
7. Locations exposed to direct sunlight.
8.
Locations where water, rain, or other moisture can get on the product.
9. Locations where oil or chemicals can get on the product.
10. Locations that are always wet or dusty, or subject to water or dust.
11. Locations where strong magnetism or strong electric fields are being generated.
Operation when the maximum flow rate range is exceeded
When the flow rate exceeds the maximum flow rate range of the FA Series Flow
Meter, the alarm message "
" will alternate on the display with the flow rate
reading. Always use this flow meter within the specified maximum flow rate range.
Installation and Piping
Piping
1. The FA Series Flow Meter is a precision instrument. Take care when handling
it. It can be damaged by dropping it or otherwise subjecting it to strong impact.
2. Whenever connecting piping to the FA Series Flow Meter, make sure that the
direction of the arrow marked on it matches the flow direction of the fluid.
3. When connecting piping, do not apply force to the bypass unit section.
4. When connecting piping, secure the main flow channel and rotate the pipe to
the suitable tightening torque range.

5. Take care to keep foreign matter from flowing into the FA Series Flow Meter.
Any rust, water droplets, oil mist, dust, or other foreign matter inside piping
that gets into the FA Series Flow Meter creates the risk of measurement error
and damage to the flow meter. Before installation, be sure to thoroughly flush
both the upstream and downstream piping (pipe cleaning) and check to make
sure there is no foreign matter present.
