New single-channel controller simplifies water treatment
Water quality plays a decisive role in many ranges - from beverage production to industrial manufacturing and municipal supply. Requirements often change; processes should nevertheless remain reliable and operation must be simple. The new DULCOMETER diaLog C Controller from ProMinent supports precisely this and is a true all-rounder.
The entry-level controller supports all ProMinent sensors, can be used as a transmitter or 2-sided controller and impresses with its intuitive operation. It also takes over 2-sided control tasks and controls two pumps precisely - for optimum dosing in industrial water treatment. The single-channel controller thus facilitates the control of dosing tasks in everyday operations and helps to make targeted use of resources.
The DULCOMETER diaLog C can be flexibly integrated into different systems and works with various sensor types. Operation is intuitive: a graphic display and clear menu navigation make it easy to use - even without prior knowledge.
"With the DULCOMETER diaLog C, we are relying on a solution that makes our customers' day-to-day 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 systems, engineering offices and industrial and municipal applications. It is suitable for applications in beverage production, the chemical industry, semiconductor manufacturing, hotels and wastewater treatment.
With this product, ProMinent is expanding its portfolio for water analysis and control and offers users a practical solution for daily operations - easy to operate, flexible to use and suitable for a wide range of applications.
Strong together: controller and sensor working together
The DULCOMETER diaLog C can be optimally combined with the new DULCOEYE LT optical sensor for fine turbidity, which ProMinent will be launching in March 2026. The sensor detects even minimal changes in the water and delivers the measurement data directly to the controller, which adjusts the dosing accordingly. This allows users to remain in control, even when general conditions vary or tasks become more complex. The interaction between DULCOMETER diaLog C and DULCOEYE LT supports reliable process control and creates transparency regarding relevant water values.
