DULCOTROL EPCa Measurement and Control Unit for DULCOEYE Sensors

DULCOEYE LT: Fine turbidity
DULCOEYE SAC: SAK, UVT, COD, BOD, TOC, and DOC

The DULCOTROL EPCa measurement and control unit for DULCOEYE sensors combines sensor technology, measuring and control technology, and optional accessories on a pre-assembled panel. This solution enables quick installation, easy commissioning, and reliable process monitoring in water treatment.

Product description

Seamlessly integrated smart sensor technology: the DULCOTROL EPCa measurement and control unit for DULCOEYE sensors.

The DULCOTROL EPCa measurement and control unit for DULCOEYE sensors is ProMinent’s pre-assembled, flexible solution for continuous online measurement in water. It serves as the common basis for the sensors in the DULCOEYE family, as the various DULCOEYE measurement parameters can be configured using the plate—for example, DULCOEYE LT for fine turbidity measurement or DULCOEYE SAC for determining measured values such as SAK, UVT, COD, BOD, TOC, and DOC.

The panel comes factory-equipped with the DULCOMETER diaLog C Controller and can optionally be expanded with suitable measurement accessories such as various flow cells, calibration When a metering pump has been installed, the capacity in litres per hour has to be determined under ... more in the glossary vessels, and solid-state verifications. Digital sensors are automatically recognized—plug-and-play instead of time-consuming configuration during commissioning or sensor replacement.

The standardized panel mounting significantly reduces planning, installation, and training efforts: Operators who use multiple DULCOEYE sensors or plan to expand their measuring point in the future benefit from a consistent operating concept, compatible accessories, and easy access to replacement parts.

The compact, robust design ensures reliable installation with high operational reliability and is designed for continuous use in drinking water and wastewater treatment, industrial process water applications, and water monitoring.
