SITRANS FS Retrofit Inline Ultrasonic Flow Measurement

SITRANS FSS100

Inline retrofit flow sensors.

The SITRANS FSS100 is the perfect choice for highly accurate flow measurement on existing or new pipes. The SITRANS FSS100 inline ultrasonic sensor package includes necessary tools for the installation of 1 to 4 path measurements. Positioning of the transducers directly in the medium enables long-term stable and accurate measurements

Overview

The SITRANS FSS100 sensor kit can be combined with transmitters SITRANS FST020 and FST030.

Key Advantages

  • Cost-effective retrofitting into existing or new pipelines, regardless of the pipe material
  • High accuracy through direct measurement in the medium
  • Extremely robust design thanks to the sensor holder being welded in
  • Minimal maintenance and long service life
  • Self-cleaning sensor surface prevents the accumulation of deposits
