Rosemount™ 404 Low Flow Conductivity Sensors
The Rosemount 404 sensor is intended to measure conductivity in clean water. The 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. 404 sensors are available with a PVC or stainless steel body.
