SITRANS FST070

SITRANS FST070

The SITRANS FST070 is a clamp-on ultrasonic flow measurement module specifically designed for seamless integration into the SIMATIC ET 200SP automation system. It supports the measurement of liquids, hydrocarbons, and gases with real-time data processing and simultaneous display of measurement values and operating status. The FST070 connects directly to FSS200 clamp-on sensors via the FS DSL interface module, eliminating the need for external signal converters and reducing integration costs.

Key Features

  • Direct integration with automation platforms such as TIA Portal and PCS 7 (SIMATIC)

  • Sensor selection and configuration directly within the TIA environment via the TIA Selector

  • Predefined faceplates allow fast and convenient setup and access

  • Eliminates the need for standalone signal converters between clamp-on sensors and automation systems

  • Cost-effective solution for applications like water treatment, small-scale metering stations, and centralized monitoring with PCS 7

  • Fully compatible with other modules in the SIMATIC ET 200SP system

  • Fast and stable digital data transmission, with update rates up to 10 ms

  • Certified for use in hazardous areas: ATEX Zone 2 / Class 1 Div 2, and Zone 0/1 / Class 1 Div 1 (when used with SITRANS I300)

Application Areas

FST070 is ideal for industries such as:

  • Chemical industry

  • Pharmaceutical manufacturing

  • District energy systems

  • Water and wastewater treatment

  • Oil and gas industry

Technical Configuration

  • Modular ET 200SP form factor, mountable alongside other ET 200SP modules in a control cabinet

  • FS DSL cable connects directly to the ET 200SP base, providing both power and data communication

  • FSS200 clamp-on sensors connect to the FST070 via FS DSL interface

  • For ATEX Zone 0/1 installations, the SITRANS I300 safety barrier must be installed between the FST070 and FS DSL to ensure intrinsic safety
