Flow Sensors

Measure and monitor to minimize unplanned downtime

Flow sensors let you measure and monitor the flow of process media, like lubricant or cooling water, in a wide range of applications.

When you are alerted that the flow has slowed or stopped, you can respond quickly and prevent an unplanned machine downtime or even system stop. This is how flow sensors, like pressure or temperature sensors, contribute to process security.

    Switching function warns of flow reduction

    Thermal flow controllers allow you to monitor process fluids. Set the limit, and the sensor switches when the fluid flow falls below a user-defined rate, for example in machine tools, on pumps and compressors.

    Their rugged housing makes Balluff flow controllers ideal for harsh industrial environments.

    With our models for thread-in or direct inline installation, you can handle a variety of requirements in many different areas of applications.


    • No moving parts, resistant to contamination
