DID

Overview

Overview

Monitoring of typical water quality parameters as well as precise control of disinfectant addition or pH adjustment is essential for many water treatment processes. Bus interface as well as data logging functionalities and intuitive user interface are a must for M&C today.

DID systems are compact measuring systems, controllers, sensors and accessories up to 3 parameters (Cl2, ClO2, H2O2, PAA, pH, ORP, conductivity). The new Grundfos by s::can DID systems are the perfect combination of s::can´s state-of-the-art digital sensor technology and Grundfos´ experience in PID controlling of dosing and disinfection processes. DID systems are designed to match perfectly with Grundfos dosing pumps, gas dosing systems as well as systems for the generation and dosing of chlorine dioxide and hypochlorite.

System configurations for tank immersion are available with up to 2 sensors for pH, ORP and conductivity, and always include temperature measurement. These variants allow measurement of water parameters directly in the tank or basin without the need for a bypass line and flow cell. The control unit can either be fixed directly at a wall or back plate, or mounted on a DIN rail in a cabinet.

Applications

DID systems are available as pre-assembled systems with bypass flow cell
or as kits for applications with tank-immersed sensors:

  • Process water
  • Food and beverage
  • Ultrafiltration and reverse osmosis
  • CIP (Cleaning-In-Place)
  • Drinking water
  • Waste water
  • Swimming pool water
  • Cooling tower

Features

Controller:

  • Intuitive plain-text operation
  • Data logger functionality
  • Up to 3 controller outputs
  • Modbus (or GENIbus) included
  • Modbus sensor interface with automatic sensor detection
  • Alarm relay output
  • Data interchange with USB stick
  • Wide-range power supply

Sensors:

  • Modbus interface to controller
  • Measuring amplifier included in sensor housing
  • Onboard storage of calibration data
  • Temperature compensation included for all sensors
  • Designed for extra-long maintenance intervals (0.5 to 1 year)
  • Precalibrated (pH, ORP, conductivity sensor)
  • 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

Compact Measuring system:

  • 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 (extension cables are available in lengths up to 20 m)
  • Probe guard included in systems for tank installation
  • Compressed-air cleaning system available as an accessory for a system for tank installation
