New single-channel controller simplifies water treatment
Water quality plays a crucial role in many areas – from beverage production and industrial manufacturing to municipal supply. Requirements often change, but processes must remain reliable and operation must be simple. The new controller DULCOMETER diaLog C from ProMinent supports you in this and is a true all-rounder.
The entry-level controller supports all ProMinent sensors, can be used as either a transmitter or a two-way controller, and impresses with its intuitive operation. It also performs two-way control tasks and precisely controls two pumps – for optimum dosing in industrial water treatment. The single-channel controller thus simplifies the control of dosing tasks in everyday operations and helps to use resources in a targeted manner.
The DULCOMETER diaLog C can be flexibly integrated into different systems and works with various sensor types. Operation is intuitive: a graphical display and clear menu navigation make it easy to use – even without prior knowledge.
‘With the DULCOMETER diaLog C, we are focusing on a solution that makes our customers' everyday work noticeably easier. Our aim is to make water treatment as simple and safe as possible, regardless of the industry or application,’ says Andreas Zühlcke, Vice President Product Management and Marketing at ProMinent.
The new controller is aimed at operators and planners of water treatment plants, engineering firms, and industrial and municipal users. It is suitable for applications in beverage production, chemicals, semiconductor manufacturing, hotels, and wastewater treatment.
With this product, ProMinent is expanding its portfolio for water analysis and control, offering users a practical solution for everyday use – easy to operate, flexible and suitable for a wide range of applications.
Strong together: controller and sensor work hand in hand
The DULCOMETER diaLog C can be optimally combined with the new DULCOEYE LT optical sensor for low turbidity, which ProMinent will launch in March 2026. The sensor detects even minimal changes in the water and sends the measurement data directly to the controller, which adjusts the dosage accordingly. This allows users to remain in control even under changing conditions or when performing more complex tasks. The interaction between the DULCOMETER diaLog C and DULCOEYE LT supports reliable process control and creates transparency with regard to relevant water values.
