(1) Instrument Overview

The SITRANS FSS100 is a time-difference-based ultrasonic flowmeter used for retrofitting existing pipelines. When used together with transmitters SITRANS FST030 or FST020, high-precision online flowmeters can be set up directly on site.

The kit provides all components and specialized tools that can be installed as flow meters with 1 to 4 channels. This kit is specifically designed for installation on empty pipes.

The SITRANS FSS100 features an online transducer (in contact with the medium), ensuring outstanding accuracy and performance.

(2) Product Features

• Affordable solutions – including all necessary retrofit components.

• SITRANS FSS100 is easy to install in pipe sizes from DN 100 to DN 3000 (4" to 120").

• No bypass installation required – can withstand pressures up to 40 bar (580 lb/sqm).

and medium temperatures between -20°C and +200°C (-4°F to +392°F).

• High precision – the larger the pipeline, the more accurate the results.

• Sturdy structure with no moving parts, achieving 100% maintenance-free and pressure-free design

• FSS100 is equipped with an IP68 protection rating transducer.

• Online transducers ensure outstanding accuracy and performance.

• Transmitters for channels 1 to 4 use SITRANS FST030, while single-channel water applications use SITRANS FST020; please select the transmitter separately.
