 14 Installing with CYA251 flow assembly
The installation angle is 90°. For turbidity measurements < 200 FNU, the backscattering of
the internal surfaces of the assembly causes distortions in the measured values.
The following diagram shows different installation scenarios in pipes, indicating whether
or not they are permitted.

 15 Orientations and positions (with CUA451 retractable assembly)
• When using reflective materials (e.g. stainless steel), the pipe diameter must be at least
100 mm (3.9 in). An onsite calibration is recommended.
• Install the sensor in places with consistent flow conditions.
• The best installation location is in the ascending pipe (item 1). Installation is also
possible in the horizontal pipe (item 5).
• Do not install in places where air spaces or bubbles occur (item 3) or where
sedimentation may occur (item 2).
• Avoid installation in the down pipe (item 4).
• When measuring turbidity < 200 FNU, the backscattering of the pipe wall causes
distortions in the measured values. For this reason, measured value adjustment with an
offset is recommended here.
• Avoid fittings downstream from pressure reduction stages which can lead to outgassing.
