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 longterm
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 tried-and-tested COS31 with
COM2x3W:
Easy measuring point changeover to optical technology
– Compatible with COS41 with COM2x3D with conversion
