Precautions for piping work
This device is a precision instrument. If even a small amount of
foreign matter like dust, moisture, or oil mist enters the device, mea-
surement error or device failure may result.
During piping work, follow the instructions below to keep foreign
matter out of the device.
(1) Before installing the device, thoroughly flush the inside of piping
that is upstream and downstream of this device to remove weld-
ing fumes and dust.
(2) Thoroughly clean the inside of piping that is directly connected to
the device.
(3) After steps (1) and (2), make sure that there are no welding fumes
and dust before installation.
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 metallic mesh or to the Micro Flow sensor chip, measure-
ment error or device failure may result.

Filter installation
• For a dedicated filter, contact the azbil Group.
• For applications with compressed air or propane, which regularly
contain oil mist, or applications where rust in the piping is expect-
ed, be sure to install a filter. Recommended type:
