► Flow in the direction of the arrow� Observe the installation direction�
► Make sure that pipe and sensor have the same internal diameter�
► Avoid deposits, accumulated gas and air in the pipe system� Install the unit so
that the measuring pipe is always completely filled with medium�
► Install in front of or in a rising pipe�
► Recommended tightening torque: 30 Nm
► Avoid disturbances on the inlet and outlet side� To do so, provide for the
following inlet and outlet pipe lengths:

DN = nominal width of the pipe
R = radius

► Mount the unit in a way that no mechanical forces are exerted on the pipe� To
do so, use angle brackets if required�
-For direct installation, fix the unit on the surface using 4 self-tapping screws
