Rosemount™ 404 Low Flow Conductivity Sensors

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.
