Field of application

Flowfit COA250 is a flow assembly for wall mounting or unsupported installation in pipes and is the ideal solution wherever sensor immersion is either impossible or undesirable. Its design speeds up sensor response and allows easy accessibility to the sensor for calibration in the air. Insensitive to clogging, it provides automatic self-venting ensuring reliable measured values at all times. Better still, with the automatic cleaning nozzle, you'll benefit from extended maintenance intervals.

Flowfit COA250 is a flow assembly for oxygen sensors with a diameter of 40mm in:

  • Wastewater treatment plants:
    - Process water treatment and monitoring
    - Effluent water monitoring

  • Drinking and process water:
    - Process water treatment and monitoring
    - Water quality monitoring in rivers, lakes or seas

  • Utilities of all industries:
    - Process water treatment and monitoring
    - Cooling water monitoring

Benefits

  • Flexible mounting options: Suitable for wall mounting or unsupported pipe installation.

  • Fast measuring values: Low assembly volume shortens sensor response times.

  • Easy and safe maintenance: Automatic sensor cleaning without process interrupt.

  • Optimized sensor accessibility: Easy sensor removal for calibration in the air.

  • Fast availability: Automatic de-aeration thanks to bottom inlet/top outlet design.

  • Robust design: Suitable for process pressures up to 6 bar (87 psi).
