  Field of application

  Liquisys COM223 is a standard transmitter for use with COS41 and COS61 oxygen sensors. It improves your operational safety thanks to continuous plausibility, process and sensor checks. Select from numerous hardware and software modules, such as relays or fieldbus communication, to adapt it exactly to your measuring task. This modularity also allows you to upgrade the transmitter at any time. A simple menu and calibration make configuration and operation fast and easy.

  
  

  The Liquisys COM223 transmitter works with Oxymax COS41 and Oxymax COS61 dissolved oxygen sensors in environmental applications, such as:

  • O₂ control in the aeration basin

  • O₂ control and monitoring of drinking water

  • Surface water monitoring

  • Process water treatment and monitoring

  • O₂ control in fish farming for optimum growth conditions

  Liquisys COM223 features the following protocols and interfaces:

  • 0/4...20 mA

  • HART

  • PROFIBUS DP

  • PROFIBUS PA

  Benefits

  • More operational safety: Continuous process check system, customized alarm configuration, calibration plausibility check.

  • Reliable oxygen control: Current input for flow rate monitoring with controller shut off or for feedforward control.

  • Easy to operate and service: Simple single-point calibration in air, air-saturated water or in the medium, direct access for manual contact control.

  • Reduced maintenance: Automatic cleaning function (with Chemoclean) triggered by alarm or limit switch.

  • Fit for every application: Numerous extensions, e.g. P(ID) controller, timer, etc., allow for flexible adaption to all processes.
