Conex measuring amplifiers: extremely user-friendly

Monitoring of typical water quality parameters as well as pre- cise control of disinfectant addition or pH adjustment is essen- tial for many water treatment processes. Grundfos offers two ranges: the Conex for well-proven stand-alone technology and the DID for full integration with digital communication and data logging.

Conex – preassembled compact measuring systems

Conex DIA and Conex DIS are preassembled measurement sta- tions. The Conex DIA is available with Cl2, ClO2, O3, pH, redox, H2O2 and PAA measurements. The controller is multilingual and offers precise measurement. The pre-assembled package is easy to install. The plain text interface makes set-up fast and easy with as little user input as possible for a reliable end result.

DID – fully digital pre-assembled compact measuring station

The new Grundfos by s::can DID systems are the perfect com- bination of s::can’s state-of-the-art digital sensor technology and Grundfos experience in PID controlling of dosing and dis- infection processes. DID systems are designed to perfectly match Grundfos dosing pumps, gas dosing systems and sys- tems for the generation and dosing of chlorine dioxide and hypochlorite.

DID systems are available as compact systems with bypass flow cell or as kits for applications with tank-immersed sen- sors. The DID is extremely easy to set up due to the pre-as- sembled and pre-calibrated configurations. Installation is easy due to the Fieldbus-based communication with both controller and sensors.

DID systems feature the following:

Automatic setting of water flow and detection of missing water flow in systems with flow cell
Probe carrier included in systems for tank installation
7.5 m cable included in systems for tank installation
Probe guard included in systems for tank installation
Temperature compensation included for all sensors
Designed for extra-long maintenance intervals (0.5 to 1 year)
Pre-calibrated sensors (pH, ORP, conductivity)
One sensor variant per parameter for all applications and measuring ranges (pH, ORP, conductivity sensors)
Diaphragm-covered amperometric sensor principle (free and total chlorine, ClO2, H2O2 and PAA)
Lowered pH dependency for free-chlorine sensors
