Field of application

Turbimax CUS52D is a smart sensor with lab accuracy that allows unattended operation of all turbidity measuring points in drinking water production and many other applications with fresh, process or salt water. You can mount it directly into your pipeline, thus saving costly bypass installations and avoiding product losses. Thanks to Memosens digital technology, the Turbimax CUS52D offers maximum process and data integrity, simple operation and allows predictive maintenance.

Turbimax CUS52D measures turbidity in:

Drinking and process water:
- From inlet to outlet in water plants
- Raw water abstraction and control
- Distribution networks
- All quality control points in water production
Saline water:
- Desalination plants
- Marine applications (e.g. monitoring of exhaust gas cleaning on ships)
Wastewater treatment plants:
- Reuse of outlet water (e.g. 4th cleaning step)
Utilities in all industries:
- From inlet to outlet in water production
- Distribution networks

Benefits

Measuring results like in the lab: Highly accurate and reliable monitoring of your water quality – even at the lowest turbidity.
Turbidity measurement without product loss: Hygienic inline measurement preserves each drop of water in the process.
Unattended operation: Intelligent design and practical accessories enable sophisticated self-cleaning capabilities and minimize maintenance.
Smart verification and calibration: Absolutely safe, liquid-free, without Formazin.
Great flexibility, simple handling: One sensor for all measuring points and all installation environments (inline or immersion).
Improved process control: Individually adaptable sensor response time.
Fast commissioning: Factory calibration and Memosens technology allow plug & play integration into your process.
