Based on the calorimetric measurement principle, the FlexFlow family can monitor both flow velocity as well as media temperature. The sensors have IO-Link and, depending on settings and connections, either two switching outputs or one switching and one analog output (4 to 20 mA or 0 to 10 V). The combination of two measuring functions in one sensor reduces the number of measuring points in closed systems. With a symmetrical, centered design, the sensors can be optimally installed in the process independent of their installation position and orientation. This helps ensure precise measurements and process safety. The PF20H and PF20S versions are suitable for hygienic and industrial applications.
