When the measurement sensor is correctly positioned in terms of immersion depth and alignment,
tighten the knurled nut with a screw-wrench (AF 27).
•
To prevent inadvertent twisting of the probe in use, tighten the grub screw.

Align the mounting grip
parallel to the pipe.
•
If the measurement sensor is immersed too far into the
pipe line, it can be retracted by unlocking the non-return pro-
tection device. To do this, slowly press the knurled nut
inwards. As with a pressure point in a car clutch, this permits
the immersion depth to be set to the precise millimetre.
•
Align the measurement sensor with the flow direction.
The flowmeter has a set flow direction. Ensure that the direction arrow on the sensor head or the
mark on the mounting handle is pointing in the media flow direction.
The measurement sensor is aligned with precision in the flow direction using the mounting handle.
An angle deviation must not be greater than ±5° from the ideal position.
