New clamp-on ultrasonic flow system Sitrans FS230

Combining the new Sitrans FST030 transmitter with dependable Sitrans FSS200 clamp-on sensors, Siemens is launching the next generation of digital clamp-on ultrasonic flow measurement technology: the Sitrans FS230. The new flow system with high accuracy and noise immunity is suitable for a broad array of industries requiring high-quality liquid flow measurement, including water and wastewater, power, food and beverage, pharmaceutical and chemical.

The Sitrans FST030 transmitter includes an innovative Digital Sensor Link that digitizes the signal at the earliest stage of measurement, resulting in an optimal signal-to-noise ratio. Due to its best-in-class 100 Hz data update rate and integrated PerformancePLUSTM algorithm, the transmitter detects even the smallest changes in flow for consistently high accuracy of 0.5 to 1 % of flow rate and a very stable zero point. Its patented pipe configuration menu allows the user to select various upstream pipe anomalies and automatically adjusts for flow profile disorders stemming from unfavorable upstream conditions. The Sitrans FST030 also offers comprehensive diagnostics that detect changes in aeration, signal quality, sonic speed, temperature and fluid type, providing a valuable window into the process and facilitating preventative maintenance.

Designed to provide a thoroughly user-friendly experience from installation through operation, the Sitrans FST030 transmitter comes equipped with simplified mounting hardware and a variety of built-in startup wizards. The Human-Machine Interface (HMI) can be customized with up to 6 different views while delivering multi-parameter measurements including mass flow, gross/standard volume flow and density. Unique support tools provide direct access to all operational and functional data, certificates and audit trails. And the transmitter's digital platform is proven in use, as it shares HMIs, menu structures and system modules with the Sitrans FCT030 Coriolis transmitter.

The Sitrans FST030 transmitter has been developed to work with the existing line of Sitrans FSS200 clamp-on ultrasonic sensors, which can be installed on pipes as large as DN 10000 (9144 mm) with no process downtime. As the sensors never make contact with the medium and do not feature any moving parts, the system requires virtually no maintenance and total cost of ownership remains low.
