Universal flow assembly
Flowfit CYA251

Flow assembly for water, wastewater and utilities

  • ©Endress+Hauser

Flowfit CYA251 is a flow assembly for nitrate/SAC, turbidity and oxygen sensors with a diameter of 40mm. It allows optimum adaption to your piping system thanks to numerous available process connections. The ruggedized material withstands even aggressive media and harsh environmental conditions and a back-pressure valve protects your process from blowing out and increases operational safety. Better still, with the automatic cleaning nozzle, you'll benefit from extended maintenance intervals.


  • Easy adaptation to your system: Process connections for almost all pipe diameters available.

  • Variable mounting options: Suitable for pipe or wall installation.

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

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

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