The SITRANS FST070 technology module is an ultrasonic flowmeter for the SIMATIC ET200SP distributed I/O. With the SITRANS FST070, data can be processed in real-time and all measurement and status data of the ultrasonic flowmeter can be visualized. It also enables direct integration with drivers and user interfaces into the Siemens TIA Portal and the SIMATIC PCS 7 process control system. All measurement data can be accessed without any additional steps. The free faceplates (TIA Portal, SIMATIC PCS 7) for the SITRANS FST070 allow integration into the control system without programming effort.
