Dissolved Oxygen Measurement

Application Areas

• Effluent treatment: optimization of the oxygen entry into the activated sludge tank (biological step) of purification plants. 
• Fish farming: Control of the oxygen entry into 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 especially designed for the use in purification plants as a self-cleaning swimming bowl
• The sensor type DO1 is bar-shaped, and can thus be easily installed in standard dip pipes for applications without necessary self-cleaning
• Use of the sensor technology in most various water qualities (pH, salt content, temperature, pollution tolerance). 
• Direct connection of the sensors to a programmable logic controller (PLC) (electroplated calibrated 4-20mA-signal) or as de-central solution with D1C controllers
• Controller (type: D1C) with staged capacities adjusted to the respective requirements and with input possibilities for all correction sizes for increasing the measurement accuracy
• Easy calibration with air or alternatively via reference measurement
• For frequently arising tasks: complete standardized measuring point as plug & play modules with ideally inter-adjusted components.
