Endress+Hauser

 COS51E measures the dissolved oxygen concentration in:

  • Wastewater treatment plants:
    – O2 control in the aeration basin
    – Process water treatment and monitoring

  • Utilities of all industries:
    – O2 control in the biological treatment
    – Process water treatment and monitoring

  • Water works:
    – Status monitoring of drinking water (oxygen enrichment, corrosion protection, etc.)
    – Water quality monitoring in rivers, lakes or seas

The sensor is suitable for hazardous area use (ATEX, FM, CSA).

 

Description

Field of application

Memosens COS51E is perfectly suited for all wastewater and utility applications including hazardous areas. The sensor is highly accurate and moisture-resistant ensuring the safety of your processes. COS51E features Memosens 2.0 digital technology. It is able to store more calibration and process data and thus provides the perfect basis for predictive maintenance and IIoT services. Designed to be low-maintenance with a long operating life, the sensor offers outstanding value for money.

Memosens COS51E measures the dissolved oxygen concentration in:
  • Wastewater treatment plants: – O2 control in the aeration basin – Process water treatment and monitoring

  • Utilities of all industries: – O2 control in the biological treatment – Process water treatment and monitoring

  • Water works: – Status monitoring of drinking water (oxygen enrichment, corrosion protection, etc.) – Water quality monitoring in rivers, lakes or seas

The sensor is suitable for hazardous area use (ATEX, FM, CSA).

Benefits

  • Wide measuring range: The amperometric measuring principle and cathode design make the sensor suitable for all wastewater applications from industrial to municipal plants.

  • High accuracy: Thanks to its amperometric, three-electrode design, the sensor provides long-term stable measurement with low drift.

  • Increased plant availability: Memosens technology and Liquiline transmitters enable plug & play for fast commissioning and sensor exchange.

  • Non-contact, inductive signal transmission ensures maximum process integrity.

  • Memosens 2.0 digital technology makes the sensor ready for predictive maintenance and IIoT services since it offers extended storage of calibration and process data.
