Process and Flow Assemblies
for Turbidity Measurement
CUA 120 / FlowFit W CUA 250
Adapter for flow assembly and flange mounting,
optionally available with spray function
Continous in-line measurement of
turbidity in aqueous media is used for
real-time measurement of non-soluble
substances in water for purposes of
monitoring, detection of operating states
and control applications.
Areas of application
•
Discharge monitoring in communal
and industrial waste water
•
Sedimentation monitoring in waste
water treatment (coagulation and
flocculation)
•
Recycling of industrial service water
•
Filter effluent and filter rupture
monitoring
•
Clear rinse cycle monitoring
•
Flotation process monitoring
•
Monitoring of closed circuits, e.g.
cooling water, product pipelines
Benefits at a glance
•
Flow assemblies featuring simple
adaptation to standard piping
•
Excellent handling properties
•
Optimized fluidic design prevents
sedimentation
•
Sensor orientation can be adapted to
individual requirements of application
•
Self-cleaning effect due to medium
flow against sensor and rejection of
water bubbles
•
Additional cleaning device employs
spray cleaning to increase sensor
maintenance intervals
•
Robust, compact design
•
Flange adapter for standardized
DN 50 flange installation

Notes for installation
•
The pipe diameter must be at least DN
100 when bright materials (VA or the
like) are used.
•
Install the sensor in places with
constant flow conditions.
Do not install it in places where air
may collect, where foam bubbles are
likely to form () or where suspended
solids may settle ().
•
Orient the sensor surface against the
medium flow.
•
Suitable for CUS 1*, CUS 4*, CUS 5,
CUS 31, CUS 41

Mounting
•
Lead connection cable through sleeve
and hexagon coupling without
twisting it.
•
Insert sensor body into the sleeve so
that the O-ring adjoins under G 1"
screw thread in the sleeve.
Note marking pin and marking hole on
the sleeve.
•
Install CUS sensor into the adapter in
such a way that the acute-angled
edge of the sensor lies opposite the
marking hole and points away from it.
The marking hole renders the sensor
orientation clearly identifiable.
