Field of application

Cleanfit CUA451 is a retractable assembly for all fields of turbidity and suspended solids measurements. It is equipped with a stop bolt, O-ring seals and a ball valve, enabling complete separation of process and sensor compartment. This allows you to access the sensor without interrupting the process or emptying the pipe or tank. Better still, benefit from increased process and operational safety and significantly reduced maintenance effort across the whole measuring point.

The Cleanfit CUA451 is a retractable turbidity assembly for:

Wastewater treatment plants:
- Sludge in the recirculation line
- Sludge centrifuge monitoring
- Primary sludge and sludge treatment
Drinking and process water:
- Sludge treatment in water works
- Filter monitoring and filter backwash
- Monitoring of phase break processes
Filter monitoring and filter backwash
Utilities of all industries:
- Sludge treatment
- Recirculation lines
- Cooling water monitoring

Benefits

One assembly for all applications: The 'one for all' principle optimizes stockholding, speeds up project handling and simplifies life cycle management.
Easy and safe maintenance: Sensor service and cleaning without process interruption.
Robust design: Process pressure up to 10 bar (145 psi), manual operation up to 2 bar (29 psi).
Convenient and time-saving operation: Rinse-water connection allows cleaning without removing sensor from the process.
