Application

The continuous measurement of the dissolved oxygen concentration is very important in many areas of water management:

  • Sewage treatment plants:Oxygen measurement and regulation in the activated sludge basin for a highly efficient biological cleaning process
  • Water monitoring: Oxygen measurement in rivers, lakes or seas as an indicator of the water quality
  • Water treatment: Oxygen measurement for status monitoring of drinking water for example (oxygen enrichment, corrosion protection etc.)
  • Fish farming: Oxygen measurement and regulation for optimum living and growth conditions
Your benefits
  • Optical technology:
    • Minimum maintenance
    • Maximum availability
  • Sensor with digital signal processing:
    • Calibration data saved in sensor
    • High degree of EMC protection thanks to digital communication with the transmitter
  • Extended maintenance intervals and a high degree of long term stability
  • Intelligent self-monitoring guarantees reliable measured values
  • No flow needed - measurement possible in still water
  • COS61D - the Liquiline sensor
    • Plug&Play: Safe communication based on Memosens protocol
    • Optionally with M12 plug for fast connection to the transmitter
  • COS61 - the Liquisys sensor

    • Compatible with COS41 with COM2x3D with conversion kit
Measuring principle
  • Sensor design:
    • Oxygen-sensitive molecules (markers) are integrated in an optically active layer (fluorescence layer).
    • The surface of the fluorescence layer is in contact with the medium.
    • The sensor optics are directed at the underside of the fluorescence layer.
  • There is an equilibrium between the oxygen partial pressure in the medium and that in the fluorescence layer:
    • If the sensor is immersed in the medium, the equilibrium is established very quickly.
  • Measuring process:
    • The sensor optics send green light pulses to the fluorescence layer.
    • The markers "answer" (fluoresce) with red light pulses.
    • The duration and intensity of the response signals is directly dependent on the oxygen contents and the partial pressure.
    • If the medium is free from oxygen, the response signals are long and very intense.
    • Oxygen molecules quench the marker molecules. As a result, the response signals are shorter and less intense.
  • Measurement result:
    • The sensor returns a signal that is in proportion to the oxygen concentration in the medium.
    • The medium temperature and air pressure are already taken into account calculated in the sensor.
    • In addition to the standard values of concentration, saturation index and partial pressure, the sensor also returns a raw measured value in μs. The value corresponds to the decay time of the fluorescence and is approx. 20 μs in air, and approx. 60 μs in media free from oxygen.

Measuring Principle Sensor Oxygen

Measuring principle Oxygen-sensitive molecules (marker) are integrated in an optical active layer (fluorescence layer). The fluorescence layer surface is in contact with the medium. The sensor optics are directed at the back of the fluorescence layer. The sensor optics transmit green light pulses to the fluorescence layer. The markers respond (fluoresce) with red light pulses. The duration and intensity of the response signals depend directly on the oxygen contents or partial pressure.
Design - Calibration data saved in sensor.
High degree of EMC protection.
