IMPORTANT
• Use gaskets having an
inner diameter greater
than the inner diameter
of the vortex owmeter
and adjacent pipes, and
ensure that they do not
protrude into the piping
line.
• When mounting on
vertical piping outdoors,
ensure that the cable
entries face the ground
(downwards). On some
types, when both ends
are cable entries, mount
so that both sides are
horizontal to the ground.
• In the case of vertical
piping, the two collars at
the top may move after
mounting. However, there
are no problems when
using in this state.
