ProMinent has announced the launch of the DULCOEYE LT, a specialised optical sensor designed for the high-precision monitoring of low turbidity levels in water. The system is engineered to meet the stringent water quality requirements of drinking water treatment, industrial process water monitoring, and wastewater management.

As the first entry in ProMinent’s new DULCOEYE optical product line, the LT model focuses on operational simplicity and long-term measurement stability.

Technical capabilities and automated maintenance

The DULCOEYE LT utilises a hydrodynamic self-cleaning principle to address the common industry challenge of sensor fouling. By maintaining a constant flow within the reservoir cell, the system reduces the manual cleaning intervals typically required for optical measurement hardware.

To ensure accuracy in fluctuating environments, the sensor features an integrated algorithm that detects and compensates for air bubbles. This digital processing helps prevent false readings that can occur in pressurised or turbulent water lines. Additional technical specifications include:

• Factory calibration for immediate plug-and-play installation.

• Compact flow reservoir design to minimise water consumption during sampling.

• Rapid response times for real-time process adjustments.

Integration with process control systems

The sensor is designed to function as a core component of a broader water treatment architecture. It integrates directly with ProMinent’s DULCOMETER diaLog C single-channel controller. This connectivity allows measurement data to be transmitted instantly, enabling the controller to automate chemical dosing based on real-time turbidity fluctuations.

According to Andreas Zühlcke, vice president of product management and marketing at ProMinent, the DULCOEYE LT aims to establish a new benchmark in optical measurement by prioritising the balance between technical precision and ease of use for global operators.

Industry applications and future expansion

While the DULCOEYE LT is initially targeted at low-range turbidity monitoring, the company has confirmed plans to expand the series. New measurement parameters are expected to be introduced in the coming months to support a wider variety of industrial and municipal applications.

The current model is now available for deployment in facilities requiring reliable monitoring for:

• Potable water supply and treatment.

• Food and beverage industrial process water.

• Public and private swimming pool filtration.

• Municipal wastewater treatment stages.
