Measuring and controlling solutions
Conex measuring amplifiers: extremely user-friendly
Monitoring of typical water quality parameters as well as precise control of disinfectant addition or pH adjustment is essential 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 stations. The Conex DIA offers measurements for Cl2, ClO2, O3, pH, redox, H2O2, and PAA. The multilingual controller ensures precise measurement, and the pre-assembled package is easy to install. The plain text interface facilitates a fast and simple setup with minimal user input, delivering reliable results.
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
