Step 2
Align the unit as shown such
that the flats are parallel with the
pipe. The arrow mark should be
upstream, if possible.
Fasten the nut, max. tightening
torque 70 Nm, while maintaining
this orientation. Finally, rotate
the top part of the sensor for
best visibility of LED display.
Minimum distance
To avoid malfunction a minimum
distance between the flow moni-
tor and bends, valves, changes in
cross-section or such like must be
observed:
• Min. 10 x pipe diameter
upstream (A).
• Min. 5 x pipe diameter down-
stream (B).
(This information refers to lami-
nar flow).
