Chapter 3. MOUNTING AND WIRING
Pipes
This device is a precision instrument. If foreign matter such as dust,
oil mist or water enters the device, it may cause measurement error or
faulty operation. When
installing piping, be sure to follow the procedures below to prevent
foreign matter from entering
the device.
(1) Before installing the
device, be sure to flush
the upstream and
downstream piping
thoroughly to remove
welding fume particulate
and dust.
(2) Be sure to wipe the inside of the pipe to be directly connected to
this device.
(3) After the above two operations are complete, check to be sure
that there is no welding fume particulate or dust, and then install
the device.
Handling Precautions
• If foreign matter cannot be fully eliminated by
flushing or wiping, or if the regular presence
of foreign matter can be expected, be sure to
install a filter. If dust, oil or moisture adheres
to the Micro Flow sensor chip, measurement
error or faulty operation may result.
