Functional principle
All non-Ex flow sensors from the FP100, FCS-… (immersion sensors) and FCI (inline sensors) series can be operated with the FS121-… external signal processor. The signal processor features 4 status LEDs and a 12-segment display for local visual monitoring. Software-based diagnostic options are also available to the user, including detection of sensor-side wire breaks and short circuits, as well as monitoring of the operating and display range for the flow rate and media temperature. The upper and lower limits of the flow range are taught in using the max./min. teach mode implemented. The flow switching point can be optionally adjusted by means of the QuickTeach function, without having to teach in the lower and upper limits of the flow range. Working on the calorimetric principle, the connectible sensors not only detect the flow rate but also the media temperature. The flow module can be operated either in IO-Link (IOL) or in standard IO (SIO) mode via the integrated IO-Link interface. In SIO mode, the switching outputs are operated in the standard way. In IOL mode, the current process values are transmitted cyclically in series as digital 32-bit values. Parametrization can be performed either via touch button or using software via the IO-Link communication interface. The parameterization via IO-Link is performed
