Process and immersion sensor for service water and
solids content measurement according to the 90°

scattered light method

The CUS 41 turbidity sensor can be
installed inline without additional sampling
systems.
Areas of application
• Sewage treatment plants
- Primary sludge
- Activated sludge
- Returned sludge
- Digested sludge
• Paper
- Monitoring sieve water

• Production
• Water monitoring
Benefits at a glance
• Measuring range from 0.01 FNU (NTU)
to 300 ppm (g/l)
• Compact shock-proof design
• Measurement according to ISO / EN
• No calibration during operation
necessary
• 3-point calibration and 1-point
adjustment
• For installations in pipes or basins
• Simple commissioning
• Optional wiper for cleaning, can be
retrofitted
• Integrated temperature measurement
• Inclined plane sensor surface uses
process flow to increase the selfcleaning
effect and repels air bubbles
• Scratch-resistant sapphire glass
measuring window
• Permissible distance between sensor
and transmitter up to 660 ft (200 m)

A measuring system consists of:
• CUS 41 sensor mounted in a flow assembly or immersion holder
• A transmitter, e.g. Liquisys M CUM 223 / 253
