November 3, 2017 - Siemens launched the Sitrans FS220 clamp-on ultrasonic flowmeter to their portfolio of digital flow measurement systems. Combining the Sitrans FST020 transmitter with Sitrans FSS200 externally mounted sensors, the Sitrans FS220 offers the most commonly required measurement functions. The flow system is designed for multiple industries requiring budget-conscious liquid flow instrumentation, including water and wastewater, power, HVAC and chemical.
The Sitrans FST020 transmitter with its integrated PerformancePLUS algorithm has been upgraded from the previous version to deliver performance, simplicity and options for customization. It measures with an accuracy of 1% of flow rate, improved zero stability resulting in minimal need to set a zero point and repeatability of 0.25% according to ISO 11631.
The large graphical display features intuitive menu navigation, multiple setup wizards, and the ability to display up to 6 user-configurable parameters on the same screen as well as to customize 5 different views. The SensorFlash microSD card provides access to all product data and certificates directly from a PC or via the transmitter’s built -in USB service port. Its datalogging and audit trail feature automatically stores up to 100 records per log of process and diagnostic parameters or changes made to device settings. This function allows operators to analyze the performance of each process and address any potential issues. And the transmitter’s digital platform shares HMIs and menu structures with the FST030 clamp-on ultrasonic transmitter as well as the FCT030 Coriolis transmitter.
The Sitrans FST020 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 10 m (394 in) with no process downtime.
