Dissolved Oxygen Measurement (not available in all locations)

Dissolved Oxygen Measurement (not available in all locations)

The measurement of "Dissolved Oxygen" indicates the amount of gaseous oxygen physically in water in units of mg/L (ppm). ProMinent offers two different sensor types for the online measurement of this parameter.

Application Areas

  • Effluent treatment: optimization of the oxygen entry into the activated sludge tank (biological step) of purification generators. 
  • Fish farming: Control of the oxygen in waters, that must be conditioned for the breeding of production animals.
  • Drinking water supply: Optimization of the aeration step in water works
  • Environmental technology: Assessment of the quality of surface waters

Our program offers the following advantages:

  • Design, measuring ranges and process connections that are tailor-made for different applications
  • The sensor type DO2 is generally designed for the use in purification systems, such as activated sludge pools, which require a self-cleaning sensor
  • The sensor type DO1 is bar-shaped, and can thus be easily installed in standard dip pipes for applications not requiring self-cleaning
  • Use of the sensor technology with water varying in quality (pH, salt content, temperature, pollution tolerance). 
  • Direct connection of the sensors to a programmable logic controller (PLC) (electroplated calibrated 4-20mA-signal) or as a stand-alone solution with ProMinent's D1C controller
  • Controller (type: D1C) with staged capacities adjusted to the respective requirements and with input possibilities for all correction sizes to increase the measurement accuracy
  • Easy calibration with air or alternatively via reference measurement
  • For frequently arising applications, complete standardized measuring point as plug & play modules with precise, internally adjusted components.
