Grease the nut (A) with greasing
paste to ensure the nut can be
loosened and tightened several
times. Note: No grease must be
applied to the sensor tip.
Remove the protective cap (B)
from the sensor tip. Insert the
unit into the T-piece.
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.
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).
