Rosemount™ 404 Low Flow Conductivity Sensors

The Rosemount 404 Low Flow Conductivity Sensor measures conductivity in clean water, combining the sensor and flow cell in one package.

The Rosemount 404 Low Flow Conductivity Sensor is intended to measure conductivity in clean water. The conductivity sensor and flow cell are combined into a single package. A small holdup volume of the flow cell allows for rapid response to sudden changes in conductivity and temperature.

Key Features

  • Conductivity sensor and flow cell combined in a single body
  • Fast response to changes in conductivity and temperature
  • No initial calibration requirements - factory-measured cell constant ensures out-of-the-box accuracy
  • Selectable cell constants of 0.01, 0.10/cm
  • EPDM O-ring seals internal parts of conductivity sensor from the process liquid
