Dissolved Oxygen Measurement
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.
